Yeah that's true as well. The sad thing is that this game sunk in the community's esteem pretty quickly. So there won't be much of an active scene willing to pay for the DLC once it comes out.
Really I think they would've made more money if at the outset they had said "the way the funding works we have to pay for making these characters by having them as DLC. They'll be available for purchase on Day 1." That's what they're saying now anyway, that it's an issue how the characters were funded in the first place.
That doesn't explain why colors were locked away when they were going to be free anyway, though.
