Beta 3 came out a little while ago. Its comming along nicely although I can't really say that it is as much as an improvement that 2.0 brought along. Out of the current main improvements the only ones that I would use would be spotlight, horizontal in some apps & maybe copy/paste. I don't use my iPod for much work. I think that one of the main improvements will be that the apps that the devs make will be able to do more.
