Well, a lot of information from a keynote and a couple tracks, so much so my head's going to explode.  But check out what I believe is going to be big news...

1. SharePoint 2010 Public Beta: November! (11/1 or 11/30, who knows, I'm hoping earlier)
2. Development on Windows 7 (or Vista...64-bit client needed but no longer do you need a local server for development!)
3. RBS: Remote Blob Storage: Basically allowing you to store content in a place other than SQL.  This is huge for media streaming
4. Access Services! Note just putting your .MDB up but converting forms and all of the other assets to SP ones...the possibilities of this one are pretty huge, given how prevalent Access is used is many enterprises

More details/info to come as the conference goes on!
