good to see youve got a good idea of whats going on except for...
...."MS winning the next gen"....
If you mean Units sold, I disagree. While I despise Sony, I see them being king of units sold for many years. it will take another gen or 2 for MS and the xbox name to be firmly entrenched in gamers minds.
Now if you take away GTA's as sony exclusives at the onset, you'd get a couple million more 360's sold. They can keep Turismos and Metal Gears. Metal Gears are dying out. How many copies sold out fo the 80 million ps2's out there? Yeah exactly.
if MS got GTA at the same time Sony did, that would be the only thing I see helping MS. But it won't happen, regardless of what rumors we hear.
