Well first of all, why did you need so long to figure this out? We had such ideas here over a year ago already.
However, it just doesn't work that way. When a generation starts, it's not that clear which console will come out on top. Also, the fanboys of each system are buying, so the sales differences aren't that big. This is why third parties release their games more equally at the beginning.
As the generation continues, it is clear which console takes the throne, and therefore, the most third party support. From now on, the sales difference will only get bigger and bigger. The losing consoles are drying up in terms of software, and their reputation gets worse too, which makes it unlikely that they'll ever make a comeback.
The market leader is usually the company that releases their new console as the last one. There was one clear exception to that rule, being the early release of the PS2 at the beginning of the 6th gen. However, this is explainable since the Dreamcast had a good start and Sony didn't want to let it sell two years without competition, and the PS1 launched quite a while earlier than the N64, so it already had a long lifespan.
In the other generations, the market leader was waiting as long as he could to get the most out of its successful console. The SNES and the N64 were late to the party, and the PS3 was too.
So as long as Sony doesn't make a move, Nintendo can just lean back and enjoy the money they got out of the Wii. Microsoft will probably be the first company to release a console next gen again, but not as early as now since the 360 will get a fair amount of marketshare and make the gaming division of Microsoft profitable, finally.
However, when Microsoft releases a new console, Sony is definitely in a fucked up position. They are getting bested by the Wii every week, and Microsoft is already taking marketshare of the next gen, so they'll just have to give up the PS3. I guess they will release their new console earlier than 9 months after the next Xbox's release.
This is basically how it works.
Also, BTFeather55, you are just ridiculous.
