You look at it from the wrong angle. "Look how many more exclusive games at launch" you say. "Look how few exclusive games there are!" is what I would respond with.
Never before has there been so much cross platforms games as it is at present time, I can count those exclusives on my hands, do you really think this will be the selling point? Launch or no launch, I know in the future there will be Japanese games out there that will never be released for Xbone, besides neither Xbone or PS4 exclusives look all that fantastic. Also this is the launch, I am way more interested in the continuing development. Besides, the real deal will be when they release it for the Japanese market with those types of games popping up. After all obviously they market casual shit for COD kiddies at the moment.
PS: don't ever, EVER mention Forza as an exclusive: it's a blatant, obvious Gran Turismo clone. They were even douchbags enough to name it in Italian, just like GT. Besides it was said that GT6 is coming for PS3 for now, but there may be coming out a PS4 version later. I know which one I'd rather play, after all Gran Turismo was a part of my childhood.
