If that is the case, then Sequential should be more than capable of making that desktop module version many would like... If it takes that few twists, you could easily do with a few buttons and knobs like "init" and "Sound good amount" etc. 
You know I'm actually likely going to trade the Kronos in for a Prophet XL very soon. So if they bring out a desktop module...I'll get that as well. 
Is it that good, that it is worth having three physical instances of it?
Seriously, if a P12 like version was made, I would actually considder it, unless Dave releases another poly with SSI chips in module form... I would really like a poly with just THAT filter, since I liked the Polysix sound quite a lot.
Unfortunately I do not have much hope for this PX module ever happening.
I personally like it that much. Not just for sentimental reasons but just the ease of programming and what you can do with the samples themselves. At first I was like "Bah, there's no pan flute, there's no pipe organ, no sitar" etc but then I realized there is, it's all in the programming. A brushed percussion mixed with a standard flute sample...and boom pan flute, pitch being modulated by an envelope and bam simulated sitar....and if that's not good enough just sample whatever you want in there. Plus the whole 8/16/32 voice modes are incredibly useful.
You'll dig a Ambience Category Raz. Each key is it's own adventure. Honestly, I can't tell you how cool it is to sample stretch one of the organic ambience or guitar drones and just have it drone on and on with some oscillators underneath to give it some weight.
I just did a bunch of drone/ambient tracks with my friend on guitar and the PX is just droning away in the back while he plays.
Well, what were you after!? A ROMpler?... It is a sampler, so if you need sitar, church organ etc. Then that is the whole point of the PX: put in your own samples

Overall I actually are impressed with the PX, and would love to try one out... But you have to understand that I tend to compare it to my Waldorf Quantum's sample features... While many things are equally good, also a lot of key points set them apart, and the things that still tickles my PX interrest is mostly its three voice modes... 8, 16 and 32, which gives functionality I cannot get with my Quantum... Another is the actual filter type, the SSI chip which gives a different character that I would like to have at my disposal.
Actually I think Quantum and PX would complement each other nicely, even if they overlap a bit.
But I have to accept, that my physical space is limited, and with both Quantum and PRO3 coming, I have no space for more keys... I am speculating about adding a certain number of modules to this rig, that would give me more varied filter tonality, rather than different synthesis, mainly because with synths the depth of what I want, 80% of their flexibilities will overlap anyway... This is why I am considdering both REV2 and PEAK again, as they have radically different filter types... Thus PX is also interresting so I am covered with 2044 SSM filter type.
Unfortunately, this will only happen if a module version is created... Or Sequential base a new poly on the SSI chips.
