Re: Iris Action
This probably doesn't have anything to do with Iris Action, but if you look on his most recent posts he has pictures of a girl who looks like the 3rd boss from the game as a teenager. Looks like he's working on a sequel.
Doubtful. Sorry to crush anyone's dreams here, but seeing as how the dev has gone back to work on the next game in the Earth Gaiden series, don't expect them to start working on anything else soon (from what I understand, Iris Action was a project designed to bring them income so they could go back to that). I think the art on the Iris Action blog following release were mostly just unrelated doodles, hence the fake mousepad designs, etc. There haven't really been many updates on the blog since the game's main release, and those made were mainly for patches, update news, and the bonus santa game. Rather, by contrast, the Earth Project devblog which had been all but silent for about a year suddenly started showing large amounts of activity.
What I will say is that Iris Action made a lot of money, and much of it very quickly as well, so I think it's likely that we will see more 'slightly ecchi' (as they described Iris Action) games from them in the future. For the time being, though, work will probably be focused solely back into the Earth Project series:
