Yesterday at TGS 2011, Sony announced that they will finally release the PlayStation Suite SDK in November. They are also expecting new games and apps to be available for the PlayStation Suite in the spring. Right now the only certified devices are the PS Vita, Xperia PLAY, Tablet S, and the upcoming Tablet P.
The SDK can run programs developed in C# on virtual machine equipped on both PS certified devices and PS Vita. It will allow developers to create content on one SDK rather than having to create different SDK’s.
I think this could really take off if other manufacturers jump onboard. For now, it will probably move a little slow, but it is a step in the right direction.
