I think WotC is in a kind of tough spot when it comes to developing new editions of D&D (and they've got to do this, if they want to make money off of D&D). As soon as it's widely believed that a new edition is coming soon, sales of current edition products are going to tank. If the game is widely playtested outside of WotC, it will leak, but some things won't show up without extensive playtesting. And if everyone is sure a new edition is coming (and this is, in fact, true) then WotC looks silly the longer they are oblique or misleading about whether or not a new edition is coming.
Personally, I like much of what I've seen of 4e, but I think it would be a bit more polished if they could take 2 years, or even one and a half, from announcement to launch. But I don't see an economically viable way to do that. And certainly pushing back the 4e launch more than a few weeks at this point would be a marketing disaster.
