The nice thing about developing software is that the work is never done. There are so many cool things that we can do to make CiviCRM a better application. I've been having some pretty good conversations with David Strauss of Four Kitchen Studios on our IRC channel (#civicrm at irc.freenode.net). Four Kitchen Studios has been a great resource for CiviCRM and were instrumental in deploying CiviCRM within Wikipedia. In the recent past, David has initiated the de-dupe and contact merge algorithm which we hope to incorporate in CiviCRM v1.8.
Some of the various things that we hope to be part of v2.0. We will use a fair amount of the design and code from the v1.x series, but at the same time make significant changes when needed.
