Think about it. Dungeons of Dredmor, in the appstore, for 5-10 dollars. For iPad. That would simply be insanely perfect. It seems like a match made in heaven, yes? Just a thought breezing in my mind, but heck, it seems like such a good idea!
While Dredmor on the iPad would probably be good, I don't think it's going to happen. Porting the entire game to a new platform, changing a lot of stuff for the touch screen controls to feel natural and also optimizing memory usage (think monster zoo's) in order to make it work... seems like a lot of work Keep in mind that they are a fairly small company, and they're already supporting and patching Dredmor for a larger amount of platforms than what the big names in the gaming industry usually do (most companies just stick to windows). And they're developing another game while doing this. So yeah, hate to burst your bubble but iOS probably won't happen.
