3.0 is a long way off. I think we won't even see GM until the end of this year. 3.0 will have three release candidates but the new styling/style won't be revealed until the last RC so it doesn't do too much good because the GDK comes with the style,
Basically none of us are going to be able to upgrade until RC3 because of that which won't be until sometime next year.
On a side note, I've been playing around with local copies and the LDAP support is great, that's what we are all going to be asking for on DreamHost in the future but I doubt it would be feasible on a shared sever.
