Co development style. Sounds close to how Sony works.

This is documented co-development. There is no on-record co-development of Guilty Gear as far as I am aware, and this still doesn't change the fact that LBP3 is not exclusive. :P

Sony Santa Monica and Sony Japan are the teams Sony use for co development when  they work with third parties to make new IP's. Demon Souls, The Order, Bloodborne, Flower, Journey and much, much more were made by Sony in tandem with third party.  LBP is exclusive to the PS platforms. Sony's definition of exclusive is different from MS, which is why people tend not to question the exclusivity of it. Think of it like Mario Kart or Super Smash.
