To be honest, I'd prefer that Sony continued to only buy studios that are already practically first party. Third party games and DLC should keep coming to all platforms simultaneously. Many users last gen were interested in Alan Wake and sad to discover it was exclusive. If this rumor is true, we'll again have a bunch of users not able to access Remedy games.
With that said, Alan Wake is one of the best games I played on my 360 and I'd love a true sequel. Hopefully, a 3rd party publisher is willing to fund it.
