There are a couple of complications regarding a wireless truly split keyboard. As you correctly assumed, the wireless communication between the halves and having separate batteries would complicate things very much and make the design more expensive.

I doubt that it'd be possible to offer a wireless UHK under $300 if we insisted to our current features and quality standards. The market is limited, it's a huge R&D effort for a small company, and a large company couldn't care less for a niche product like this.
