I think I may know where they are going with this Back in Black storyline for Spidey....bear with me...
At the end of The Other, Peter's old skin, now empowered with the evil spider crap or whatever, coccooned up in a church....what else happened in a church in the SPider-Man mythos? You're ou tof time, he originaly got rid of the symbiote there (the black costume), and it bonded with Brock to form Venom.
Now, supposed that this cocoon hatches, this evil Parker comes out, and dons the black suit in order to take Peter out (in the mean way, not on a date or anything).
Oh, this Nega-Parker would also have blond hair...dum dum dum (yeah, he'd be called Ben Reilly too)
