The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
Business-wise I can perfectly understand their decision - the money is in the 5e space.
Personally, I would prefer a version with OSR/OSE stats, though (or even better, something Year Zero-compatible, but based on the realities of the market, that's not something I would actually expect to see, while 5e+OSR at least seems to happen once in a while).
