I really hope the Bioshock one also has DmC in it. I mean, think how awesome that would be; normal Bioshock stage, and then wham, the city starts tearing apart.
If there is no resistance rep then Insomiac didn't want one, its simple as that. But we won't know until the game ships out, though after that someone is probably going to hack the game and find unfinished data for certain things, like characters or stages.
It's a possibility that Insomniac thought Hybrid wasn't really a character and therefore the series should be better represented as stages and items.
Or maybe SuperBot is lying and we have unlockable characters on disc.
