@ursaber: Err... Why would she appear on MM if she was on Spiderverse?? I don't think any of one series' supporting characters appears on another (other than guest appearances here and there), except Jonah I think who was both on Silk and ASM. Plus I disagree with ur last line, PAD is cool, and I still think any of the current writers/teams would be a better place for her than Iron Man+Bendis.
Because of Bendis who writes MM and IIM. If MJ was shifted to an Iron Man book, completely out of the Spider Offices, than the chance for her to appear in another Spider book is very possible.
PAD, Peter David right. His Spider Man 2099 started out good but it got progressively more boring. I say this as someone who loves Spider Man 2099.
Still I stay my ground. MJ in Limbo rather than have her outside ASM or in ASM with Slott writing it. LIMBO!
