This whole thing is ridiculous, as if he did not know on what other platform(s) a big titles like this one is coming?
He needs to demonstrate the "win-win" thing, not just say it, right now XB1/360 owners do not "win" anything, this game was going to be released on their system anyway, however PS/PC (maybe even Wii U) owners certainly loose an option.
So as far as customers go, nobody wins (it's not a win if you have to buy a new console because you want to play game X that was obviously planned on a device you already own...
So the companies involved do have some potential "wins" MS is poised to sell a few consoles, especially considering that the game will not have a better PS4 version and an even better PC version (depending on your config) to compare it to....
Now that also shows you the difference in attitude, when Sony saw they may need some 3rd person action shooter to respond to Gears of War (I assume a lot of things here) they got one of their studio to build something from scratch, a new world, characters, etc. they took a risk. MS on the other hand, they went out, and placed a bid to have a game taken away from gamers on other platforms, and Square Enix took the money.
I am still not sure who's worst in this, MS for corrupting, Square for being corrupt? MS/Square for implying they don't know what will happen once the timed exclusivity clause expire?
I would much rather companies go in and create games than prevent them from being published on competing platforms (ideally even first party titles would show up at least on PC, that would make preservation of old games SO much easier).
