External bearing BB questions...
Ok, here's my question... What is the inter-compatibility between the Shimano, TruVativ, and FSA external bearing systems?
Reason I ask is I currently have a Bontrager(TruVativ) crank running on a GXP BB and I'm looking on e-bay for an lesser priced compact for a few more hilly rides later this year (IE: Marin Century out in Cali). I would really like to not have to bother with swapping out BB's or having to specifically look for another TruVativ, leaving me open to the option of finding an FSA (Shimano is too expensive).
Has anyone actually confirmed or denied that the GXP and MegaEXO will or will not work together?

Know a friendly bike mechanic? One of our local boys doesn't have a sniff but has ALL the books and is willing to share. Buy him something nice.

There are lots of people in the mech forum who do know the answer to this, so rest assured your question will be answered. I think there is compatibility across the various brands here, especially between FSA and Truvativ.

They are the same. In fact a lot of people use FSA or Truvative BBs with Shimano cranks because they are sealed better. They seem smoother too. I expect this won't always be true. They will figure out to make each slightly different to make them proprietary.

I figure the only way they'd be able to make them proprietary would be different spline diameters or spline length and cup widths. I'm sure they will think of something with the next great innovation.
