There is a rumor going around that Insomniac Games, a studio that has been historically PS3 exclusive will be going multiplatform. Considering the fact that Insomniac Games is an independent developer, this is completely feasible.
Insomniac Games is an independent developer that is not owned by Sony. The studio has historically developed exclusively for the Playstation brand. However, according to IGN a â€œtrusted sourceâ€ has revealed at GDC that the studio will be developing on both the Xbox 360 and PS3 in the future.
This is completely possible and probably most likely given how expensive it is to develop next gen games. Even Bungie, a former Microsoft studio is rumored to be working on a multiplatform, Xbox 360/PS3 game currently.
However, donâ€™t expect Ratchet & Clank or Resistance to pop up on the Xbox 360 anytime soon. According to the US Trademark database Sony owns the trademark for both titles. The multiplatform title will most likely be a new IP with a major publisher like Electronic Arts. I suspect we wonâ€™t be seeing the game for sometime as Insomniac Games is currently busy working on Resistance 3.
