I remember them saying they were planning on allowing HTML5 stuff, and just the other day IGN reported they dropped the "must have an office" requirement. They also dropped their thresholds of units shipped/sold before getting paid--you get paid from sale #1 now. I hope it doesn't turn out to be a pipe dream, but Wii U support with C2 would be unbelievable.
BTW, if they do it, we need to make teams here to crank some stuff out.
