Stats I read online paint a similar Sony(1st), Nintendo(2nd), Microsoft(3rd) picture but put it more like 45%, 28%, 25%, meaning MS has hardly "lost", but rather is just in third place.
When you take Nintendo out of the picture and look strictly at Sony and Microsoft, the numbers look so much worse for Microsoft. Unless they can score some important exclusives, I just don't see them continuing to produce future generations of game consoles. So all of you fighting this merger, I hope that you enjoy your Sony game console monopoly.
Should that be the GameCube? It’s successor the Wii was went they stopped trying to keep up tech-wise.
