Adminbar - WP 3.1 / BP 1.28 | Should I see new?

Question...a quick one...

I should have the new adminbar (with avatar, search, etc) with BP active, correct?

Seems when I activate BP, site reverts to "old" adminbar.

WP 3.1
BP 1.28
WPMU Fun Theme
Live (with adminbar shown to nonlogged temporarily)

When I deactivate BP, new adminbar returns.

Could someone please clarify, so I can be sure I am on the right track in thinking I have an error?
