Gusty, the newest Ubuntu was just released.
I am downloading it right now to give it a test run.
get it here :
Here is the early beta Wubi installer in case you dont want to partition your hard drive,
You have CD rom problems, or you just dont want to waste a CD to try it out
From the package list, I can see we are not going to get Blender 2.45, the only thing in the stable repository is blender 2.44
No Compiz fusion or Beryl either, but that is because it is still in beta development.
The rest looks pretty cool though, I am looking forward to giving it a try tonight.
