New IP, preferably something non Sci-fi or Fantasy. There will always be room for more of those. But It'd be interesting to be able to play more role-playing games with a more realistic setting (historic would be interesting for example). Also, more moral ambiguity... akin to that CD Projekt Red have shown in their Witcher series. I'm not saying that Black Isle or Obsidian have put out games with overly arbitrary moral choices. But of all the CRPGs I've played The Witcher series made me think of every action I made, they felt more real than other actions in other RPGs. And one last thing, perhaps a game with a setting devoid of violence would be interesting as well.
