Before heading off to Charlotte, North Carolina, for this weekend's HeroesCon, Frank Cho offers a tantalizing clue to his secret follow-up to Marvel's Savage Wolverine in the form of a cover detail that clearly shows Emma Frost (in full below), along with what may be Angel in his classic X-Men costume. Those other elements are anybody's guess.

"Now, people have asked me what’s coming up after my Savage Wolverine run," Cho writes. "Well, gang, Marvel will announce it soon. In fact, I’ve just received the full script this week and just started drawing it. It’s a doozy."

This weekend he'll be at Artists Alley table AA-1503, where maybe you can pry a few more clues from him.
