I saw a topic like this in the DC forum, and I'd figure I'd ask here given that Priest wrote the Spider-Force miniseries last year. His fifty issue run on Deathstroke is coming to a close, and he'll likely want to replace it with something... perhaps an ongoing Marvel book now that he's back in the Marvel game? He's historically been closer to Marvel, what with him getting his start as an editor there in the '80s (as Jim Owsley), and having many stories written including the landmark Black Panther title, though he's done quite a bit for DC as well.
I suggested in the past that based on the Spider-Force series Priest could write a Kaine Parker comic, though others suggested the idea of a comic called The Scarlet Spiders co-starring both Ben Reilly and Kaine Parker, where the two work out their differences and put that chapter behind them. Outside of just Spider books, I wouldn't mind him being given an X-book as part of Dawn of X. In fact, I think an X-Factor comic would suit him well what with the world of snark nature of it.
What do you guys think?
