You definitely show your Sony pride!!
Too bad your passion for Sony seems to make your somewhat valid point sound silly. So, in your world, if the PS3 beats the 360 by 5-10 miilion, there wiil not be any suppport for microsofts consoles in the future? Just the opposite, it shows the software developers that they shouldn't put so much faith in supporting just one cosole, but all of them.
Hmm...I don't like Sony as much as you think. If Sony did what MS did this gen I would have hated them as well. Its the act that counts, not the name. Its one of the reasons I don't dislike nintendo (I actually like their staff cause they are quite down to earth compared to Sony and MS.) even though I don't own a single nintendo console.
360 will have support, but not from MS, but from 3rd party. I don't think they will stop selling the 360 like the original xbox though.
