Yes but as GP points out that promise is a part of the reason why there will ever be a 2.0 in the first place. People over paid for V1 because they were buying a v1-v2 package. People who would have passed on V1 were willing to buy it because of the promise of polished V2 for no cost. Without the promise he wouldn't have done nearly so well and perhaps would have folded before V2 became a reality.
If anything V2 should have been reduced in scope and shipped sooner because of the promise, not drawn out so that you kill revenue giving free upgrades.
