The NetEase partnership gives me even more reason to believe that Bungie plans on selling the rights to Destiny to Activsion at some point. I've had this thought for many months, even more so ever since Warmind came out. I just get the impression that Bungie wants out, and wants to work on something else.
Destiny is too stressful and far too ambitious. A mobile game or BR game of some kind will probably be a lot easier to develop and support. I can definitely see Vicarious Visions taking over core development, while at most, Bungie merely acts as a distant consultant, going forward.
Or maybe they'll be a multi IP studio, but they clearly have issues managing just one, despite their size and capacity.
