Yeah like 28.9 or something, but why and what's it compatible with and how long are they going to provide BBs for it I wonder?

It stands for durable unified BB and it's SRAM's one BB to rule them all. They'll sack off GXP and 30mm axles for just one 28.9mm axle.
Or so they said who knows if they actually did it.

Using a bearing with a 30mm ID without having the inner race being naked against the axle?

It's just under 30mm and asymmetrical.
