Mercenaries: Reunion is a scam

Why the hell can't I use the rest of the Mercenaries crew?! I buy this to find out I can't pair up Tribal Sheva and Heavy Metal Chris? Come on Capcom, I know you're greedy as fuck, but come on. Would it REALLY be that hard to make a super Mercenaries mode with both the original RE5 Mercenaries characters and the new DLC characters?

Oh wait, you're probably going to release it as DLC in a year and charge us.
