One last thing before the news is out...
I'm kinda hoping it is some sort of a misdirection.
That said, a pair of limited series does sound exactly like something this writer would sign up for.
Accounting for that, wasn't their some talk of the "Ultimate" universe making a comeback a little while ago? That being the case would certainly line up with this writer and there being an "X"-related component.
Never mind that it would account for the copy in the ad.
