Only one oscillator
Sort of par for the course for semi-modulars in this price range (see, for example, Pittsburgh Modular System 10 and Dark Energy). Ultimately, the intention is for it to be part of a bigger modular system. The three-Mother rack costs almost nothing ($80), and they really seem to be encouraging multi-Mother systems.
So the single-oscillator doesn't bother me. No, the thing that gives me pause is the pared-down envelope generator. This falls short of the classic Minimoog ADS. Again, you're supposed to add stuff to it, but I'd have preferred a decent EG to start with.
The Mother-32 is tempting, but I don't see one in my own personal future. I'm more likely to get another Minitaur, which has two oscillators already and two five-stage EGs. If I ever dive into modular, it will be more likely with a Pittsburgh Modular system, and start down the road of slowly building a huge Frankenstein.
