Can someone tell me if it will publish apple apps. Rumor says it can
mm it's possible that a developer who makes ios apps would pay for a PS mobile SDK license and port their work. how many developers will get on board with that is entirely up to them. you won't be seeing your favorite ios apps or android apps overnight though, until things are either developed in tandem for all formats. and i think i readsomewhere the SDK wont be out til november so it's all gonna take time.
tl;dr - it's possible, but not straightforward as u might assume.
