Arriving in 2015
Archie's Dawn of X storyline (in which the original Mega Man, as well as Proto Man, meets X and Zero) is going to unfold over the course of four issues, but for some -- hunting and collecting comics isn't a desirable activity. That's perfectly understandable, and as luck would have it Archie provides paperback collections of major arcs in a giant easy to digest $10 book.
It appears as if the whole Dawn of X narrative will be included over the course of 104 pages, but there's one catch -- it won't be out until 2015. So far all you X fans out there, either get your pre-order out of the way, or sit tight!
