I hesitate to give an exact date, as we've already missed a few deadlines on OCS 2.0 -- however, we're working on integrating electronic registration payment at the moment, and then we'll need to do a little final testing. Those are the only two tasks left for this release.
FYI, the initial release of OCS 2.0 will *not* include migration tools to allow importing of OCS 1.x conferences. We'll be implementing this for a future release, but its scope may be limited as the two applications are quite different.
If you're comfortable playing with CVS and want to try the pre-release code to see if it'll suit you, the PKP CVS repository is open -- see http://pkp.sfu.ca/ocs2/README-CVS
