If Spencer has declined to confirm how long that duration is set for, it seems that Rise of the Tomb Raider won´t be on PS4 in this generation. 

Eh, that's what Phil himself said. It's not that hard to figure out if you apply some reading comprehension. Whether it's about only this game or the "IP of substance" is highly irrelevant, because the deal has a duration. I can't believe some people still think it could not be timed...

I can already prove you wrong, because they are working on a Tomb Raider game for PS4 and PC, mentioned by Crystal Dynamics themselves. AND like I said, unless you believe the duration is more than 2 years, rise of the tomb raider WILL come to other platforms.  It will be a late port, but it will be extra millions of sales for Square Enix. Do you think they'd just skip this game and release the next one on other platforms? That would be stupid.

Yes, because of some vague wording we are to believe that this game is fully exclusive to XOne, as some here still try to spin.

Of course, they (MS or SE) could have been honest and admitted it's fully exclusive, like, for example:

I'll be so bold as to say it is guaranteed to be on PC because that won't have strings attached. Sony will want to extract a pound of flesh from SE for it to go on PS4 so SE will have pros and cons to weigh up. But I don't there is any credibility to the assertion that MS has a hold over the game beyond 12 months after launch, and it could be as brief as 31 Dec 2015.

I do not believe Sony can extract anything from SE to bring TR to the PS4.  SE already have publishing contracts with Sony and I am sure that will be enough to bring the game to the platform.  If anything, the it takes 6months to a year to get on the PS platform, then it will be up to SE to provide some incentives to get PS gamers to purchase the game more than anything else.
