Not the same engineers at all. Crank and BB engineering takes place at Truvativ, which has been based in San Luis Obispo since before SRAM acquired them. It's a separate engineering unit altogether to Avid (now simply called SRAM, since the Avid name wasn't doing so well anymore).
Regarding 28mm spindles, what we were told is that they were looking for the best compromise between bearing and spindle size as well as room to make the new seals they wanted. It's very tricky work. We won't really know what their final grade should be until we (and others) start riding the stuff and can comment on durability of several versions of the new stuff.
