I wouldn't stop me from playing, if I actually had an active group at this point that is.
But it has had a similar effect on me, since I am no longer working on monsters, items, house rules and other stuff for 3e. But that isn't because I don't see a point on making 3e material, it will certainly have plenty of use until then and even after, but 4e has forced me to rethink everything I've done and plan to do.
That, and it seems a lot of stuff I wanted to make or fix is already being taken care of in 4e, and by people with far more talent than I.
