One thing is for sure, if the PS3 keeps selling and Sony keep supporting it then 3rd parties will still release games for it and it can last for a long time. It all depends on if Sony pull the plug or not, if they don't then neither will 3rd parties because the PS3 will have a respectable userbase no matter what happens from here on out.
I am almost certain that Microsoft will be planning the next Xbox for 2010 release, Sony are best served to continue with the PS3 and forget about what Microsoft do.
