Reporting services, Infinity, Web 2.0 and Social Networking. If you had a chance to hit Tim Wolf's session you'd have seen some slick stuff that is coming in v5.5 with regards to BBNC supporting Social networking.
There was also some stuff on Facebook integration, not sure if that'll make v5.5.

Also a move towards better documentation for the API which I'm happy about.
Marc Chardon pointed out that Blackbaud's API has been 'open' from day 1 while they never officially support (or document in some cases) or marketed it as some other companies have done so. Open API is just a buzz word anyway.

Good stuff though. I met a few of you all and it was a productive few days.
