Sure, there will be clones, but if you're playing with a group of people, it really shouldn't be a problem.
That is, of course, unless you all want to play as a team of Wolverines, like from that issue from the Exiles. I have a feeling there are going to be a lot of multiple costumes for the characters.
Also, I saw Cloak in this game already! I hope he'll be playable and not just a NPC.
