One thing that I think speaks well for the Prophet '08 is the fact that YouTube is loaded with many videos in which the instrument is used to make music. It doesn't seem to be a popular noise-maker, but much more inspires its users to make actual pieces of music - very much in the synthesizer domain - and many of them are quite impressive.
It will be interesting to see if the Rev2 inspires the same response. It certainly should, but unfortunately, the instrument is still in the first phase of its life when users are excited and prone to make only short demonstrations in a rush. After the limelight has been passed to other new synthesizers, hopefully the Rev2 will age and mellow and be viewed at last as a serious musical instrument fit for producing serious compositions.
Firstly, and don't take this the wrong way, I've seen it often.. it sounds more like your thoughts are just trying to justify why you want to keep the '08(s) and not advance to the next level. I see it all the time. Everything you've said is pretty much a moot point concerning actual capability and usability. Everything the Prophet 08 is to you, the Rev2 is to me (and others). Many of us never had a Prophet 08 (though I played with one quite a few times though it didn't quite fit the bill overall for me in a few areas - areas that have been amply addressed by the Rev2).
In other words you seem to be hypothesising reasons to stick with the 08 over the Rev2s because of the hassles of selling the 08 or finding extra cash for a '2, but some of us just had to go spend £1200 - £1900 on these things without a prophet 08 to sell towards it so I can't see that as any argument. Sell the 08s asap before their prices drop even further and get a Rev2, it's awesome in so many ways the Prophet 08 never was. And I mean all those little additions, the general feel, the keybed, the proper power cable, the beautiful buttons (use and looks), the refined inspiring layout for programming, then the actual sound enhancements which I feel you, and some others, are playing down to make it seem like Prophet 08 is 'basically as good'. It isn't. If this was a different synth by a different company vs a Prophet 08 it would be more clear, but because it's obviously masquerading under the Prophet 08 mk2 banner to many I feel its making people ignore the genuine greatness of the REV2 as its own thing.
I too like the guy above have made a ton of *real* music and custom sounds with Rev2 since I've had it, it replaced other synths in my tracks (some inc vintage VCO polys) and I find it inspiring, productive and capable of almost anything I can think of in terms of what I need in actual music. There is no 'honeymoon' period here or blind devotion to it as a shiny new toy that can only be used for YT demos or something, it's straight into the studio, it's making music, making sounds the Prophet 08 couldn't.. easily, sounding better than the 08 in how organic and rich it is compared to the 08 and with tasteful use of the FX section opens up a whole new universe of inspiring sounds without going down the rabbit hole of confusion/drowning in FX like some other modern analogs do.
In other words it's a stunning synth every bit as good as the prophet 08 and then 50% better again. There is zero argument for preferring the 08 over the rev2, unless you want to get seriously nerdy and go on about the logo (I honestly prefer the new logo was never a fan of the gaudy old font on the old prophets personally this looks built for the future not the past), as for the screen I have good eyesight and have no issues with it, it's really good and has a massive viewing angle, I can read it from 6 feet away it's so sharp and vivid, and it looks classy too because being black OLED it just blends in with the analog ethos more and keeps it focussed on the controls and playing. The screen doesn't need using that much at all anyway, rev2 is definitely far better thought out than the 08 when it comes to menus and programming and hands on.
So, what I'm saying is until you have one all your text is just supposition and justification for keeping what you have without taking a risk or 'upgrading' (and believe me it's an upgrade and then some), and lets not even joke about starting rumours of 'older sounds better' because the Prophet 08 is, as we know, one of the most marmite synths on the market, many people hate it as much as love it and Rev2 deserves to fly on its own sound, powers and qualities without being held back or saddled with falsehoods by disgruntled P'08 owners. It can sound like a Prophet 08 but it doesn't have to, it can sound far far better and do far far more. That is all there is to that debate. Other than if you can justify/afford to buy it. If you have (3?) prophet 08s I really don't know what's stopping you, you have assets to sell off to get you it. You don't need more than one prophet 08 esp if you got a 16 voice rev2. I will be selling some of my old synths because I no longer need then with Rev2 on board. In fact I'll get down to just the rev2 a piano and guitar and I'll be done, after years of collecting old and new synths, buying and selling, had over 100 synths in the past 15 years, those days are over. It's time for music not synth hunting, and Rev2 has been the first new synth that's finally allowed me to feel that way.
YMMV but I seriously doubt it.
p.s I've got the 8 voice version but am seriously considering buying the board in the future when I have spare cash, the synth is that good and even in non-stacked mode I've made some gorgeous long release sounds that get note stealing even with 8 voice poly, so 16 voice would make this a world beater. It's also perfect for those who want to layer and multi-sequence, and entire analog sound creation universe in one sexy board! NO messing around with 2 or more space taking units + loads of cables/FX boxes.
