Vista, HD-DVD, even the X-Box 360 and their "red ring of death" shows that MS is more inclined to "get a product out there" than to actually work on a project and refine it.
Haven't we seen that from most of the players though? Everything is on an urgent timeline to push to market. It appears that many don't have the luxury of perfecting before first launch. Heck, the same thing happens on our development side. People want it now. I understand the challenges afoot though, MS does have a history. ;)
Whatever happens, let's just hope it is for the best.
