@Trickysticks, I guess you _could_ call it problems, but Colino is getting married, and is moving from USA to England, and I'll bet you that takes up quite a lot of his free time. Furthermore, he's also working on other games than AKS2, so expect news about those when he gets settled in Britain.
Actually Kuroi, he talked about AKS3. He said AKS2 would be his last idle game. There'd be lots of updates coming, but never AKS3, so in a sense he talked about it anyways.
