Since PS4 almost has a 2:1 sales lead over Xbone, isnt it almost franchise suicide to make a game exclusive to xbox? Even if it comes out 6 months later on PS4, its hype will have entirely died off by then and PS4 gamers wont be interested in a game that theyre getting late. 

That depends, do you think halo and gears have or are comitting suicide?

If Ryse 2 came out on PS4 today I think it would see some solid sales, so no, it's not suicide. Yet. Resident Evil survived a few releases on GC after all ;)

It depends on whether how much money microsoft willing to throw at them.. You can be sure the creators have thought well over if it is profitable the offer microsft gives.. What is more important imo., is how much microsoft will allow xbox to spend when it still doesnt show results.. This cant keep up and it could force microsft to sell the xbox division.. Another option would be to completely spin off the divison but that is a death sentence since they dont have the studios to maintain exclusive content and without money from their parent company they dont have the resspurcew to buy exclusives like dead rising, titanfall and now tomb raider.

games sell on xbox very good.

It depends on the fan bases really. Certain games no one cares got money hated. But stuff like Tomb Raider did. We'll see once TR comes out. To see if it was really worth it to MS. All as we know enough people got so mad, they only sell the same amount they would of gotten if it was multi platform. And the extra investment was pointless. It is also dumb in the overall picture. If Sony forever sells like it is now. And Xbox never gets a boost. These deals are worthless.

Using the word "suicide" here is a bit too much, don't ya think?

Like everything, if the game is good and can interest some gamers it will survive, Titanfall has passed 2 million only on Xbox one without the digital numbers that is pretty good...

Not if MS are funding the project or publishing, no.

No, the X1 is still ahead of 360 for the same timeframe, also the attach rate at lower sales are often higher so franschises will do good :).
