It probably depends a bit on what kind of build you have, the plugin support you need or will need, and what kind of timeframe you are looking to get this done by.

I can give some rough ideas regardless. sbt 0.9 has the major features done, but needs a couple of months to stabilize and (basically guessing here) another couple of months to get main plugins converted*. I'm basing this off of what happened with 0.6.x, which was similar but smaller in scope. I plan to start publishing binaries with 0.9.5 (in a couple weeks or so) and I'd guess that is when wider involvement will happen.

*Certainly I wouldn't call it a lot of chatter, but there is already some work on IDE integration[1,2], proguard[3], and Lifty[4].
