Personally, I think I would prefer they hold the game back and do whatever patches or updates they need to help with performance, rather than release a game they know is buggy. I guess it's nice that they're actually telling us before people buy the game, and they will be releasing updates. But frankly to me this feels like they're going to be fighting an uphill battle when they launch the game. Plenty of people won't see this message, and just buy the game expecting it to work, then turn sour due to the poor performance. You could end up with people refunding the game and never coming back with stuff like that.
