1. Some might disagree, but I think the mini series approach is a pretty good idea. There are quite a few advantages over giving him another ongoing.
2. I am very interested in how Cullen Bunn is going to pull this one off. To be honest, I had a feeling this was going to be a new thing. Yeah, my "all the dead Deadpool's rise for revenge!" idea was okay, but a little obvious. Would have been a fun way to take a poke at Blackest Night, though.
I feel I can be forgiven for a little speculation, though. The ending to Deadpool Kills Deadpool was a tad ambiguous . . .
