Are Sony fans worried about XB1's 15 exclusives?

Sony has given me no reason to worry after the last 3-4 years of them vs MS. In fact, MS has been pretty worrisome.

I wonder how many of those 15 err..."exclusives" will end up on PS4. Not that the PS4 needs it, but that has been the case with a lot of them in this last gen.
