I would really hate to see that happen to TESO, since fans are bound to go nuts as soon as they get some basic information regarding classes and such and they will be screaming for a launch date. For all that is worth Zenemax, I personally wouldn't mind if you postopned the launch even till 2015 if necessary, as long as you take your time to do all that needs to be done. If halfway through development you decide some major feature needs overhauling or complete replacement you have my blessing (xDDDD) to completely scrap it and start over.
I hope more people will join my plea and let Zenemax know that we'd rather have a complete product instead of a half-baked bagel! Take your time and knock us off our feet when the game is done!
