This looks a lot like a X0XB0X with better case design and a battery. Which is pretty nice. The 4-Pole OTA filter is the Roland TB-303 one that people seem to like, again, like the x0xb0x. Hmmm. I hope they are giving credit where its due.

I'm pretty sure that the Jupiter 6 and Jupiter 8 filters use OTAs. Perhaps that's what you were thinking of.
It seems like this could be a very nice unit, although far from the first modern thing to recreate the SH-101 (for a very recent example, see Behringer's attempt)
That being said I find it a bit odd to make such a fuss about rechargeable batteries as the original Roland unit already had battery power (as did the TB-303 and TR-606). You can simply put rechargeable batteries in them.
Worth noting that you can still buy the original Roland SH-101 for less than even the "early bee" price on kickstarter.
