So the new Deadpool Merc With a Mouth that's starting in July is going to be another ongoing. First story arc pits him alongside his Marvel Zombie counterpart who first appeared in Marvel Zombies 3 and is in the current Marvel Zombies 4.

So that makes two ongoings for Deadpool, along with a current running five parter (Suicide Kings), a recent one shot (Game of Death), his appearances in Cable, X-Force (both due to the Messiah Wars crossover event) and Thunderbolts (due to a Dark Reign tie in). Not to mention his appearance in the upcoming Wolverine Origins movie.

I think I'm officially Deadpool'd out.
