From Candorville.com To be honest, I'd pay to see it no matter what. But I'm still hoping it's Kirk's brother Sam (one of the stories from the IDW comics seemed to suggest we'd be seeing more of him, but he hasn't resurfaced in the comics, yet).
Agreed. I don't necessarily hate the idea of revisiting the character of Khan, but I think it would have been a creatively bankrupt decision at this stage in Nu-Trek's life. I want exciting new adventures, not slightly-different-versions-of-the-same-ones. That said, I'm not putting it past Abrams to sneak Khan in there somewhere anyway. He's already hinted he'd considered putting the Botany Bay in Trek 09 as an after-the-credits teaser, and I can certainly see him managing to run Khan's story in parallel with John Harrison somehow. A bit like how Chris Nolan handled Harvey Dent/Two Face (we all expected it to lead in to the second sequel, so we were surprised when he actually croaked at the end of TDK).
