I see the imminent upcoming Oberheim synth as being a much more polarizing product than the P5/10 Rev 4 was. Some people are going to be willing to sell an organ (both types if necessary) to get one, while others will reject it for a laundry list of reasons.
I think these vintage reissues are targeted at the Generation-X demographic, those of us who grew up listening to classic rock of the 70s, new wave of the 80s, etc. This particular age range is selected because its both most interested in the specific sound of these instruments because it will touch a nostalgic nerve, and also the most likely demographic to have the expendable income to be capable of buying them.
My P10 signal is currently going through a Boss CE2W, then a Mobius, then a Timeline, then OTO Bam, which means the total synth + FX constitutes almost a $6.5K instrument.... but sonically, the results are worth every penny, to me. I totally get folks who won't or can't spend as much on gear. I can remember the days where I had to sell all of the music gear just to be able to pay for books, computer hardware and tuition I needed for college. So for me, the reissue of the Prophet 10 was kind of a dream come true -- a reward for all those times I was struggling and far removed from being able to afford the kind of gear I really wanted.
An OBX/a is another bucket list item for me... I totally get that not everyone grew up with that sound, and not everyone else is going to have that same connection with the sound. And that's fine, there are plenty of cost effective options out there.
