This is (if the rumours are to be believed) the new Moog Voyager OS, with OS presumably standing for Old School. It's an all analog synth with no patch storage, no MIDI and no display - essentially a refreshed version of the 37 year-old Minimoog design. Presumably it will be cheaper than a Voyager, more expensive than a Little Phatty. I like the idea of a synth as a simple instrument like an electric guitar, something you plug in, tweak a bit and play. This could be perfect for (well-off) keyboard players in guitar bands who want to look cool and make cool noises, but are never going to need to connnect it to anything else. Also, if every single person who's ever gone onto a synth forum and said "yeah, I don't want all that modern crap, I just want a totally pure analog synth" buys one, then Moog will be rich beyond their wildest dreams.
UPDATE: Here's the official page , with a price: $2595 - $500 less than the full Voyager, $1,200 more than the Phatty...
