Well found this on KryptonSite.com- Michael Rosenbaum posted today on Twitter that good news is coming, but that a Smallville return is not in the cards.
"Sorry. It's not Smallville related. I've already stated that I'm not returning. I'd never lead you guys on like that. I appreciate your support," he wrote.
He did, however, reveal he has a funny role in Christian Slater's upcoming FOX TV pilot about a group of computer hackers. More information about that project should be available soon. Additionally, as soon as we know more about Michael's "exciting news" you'll be able to read about it on kryptonsite homepage. Well to me this is some straight up BS! It's only for a couple episode's maybe 2-7 not the whole season, you get paid! right now I havent seen you on anything else! Just come back for the fans! and how the hell is it not Smallville related?
Well it looks like MR just dug his own smallville grave......maybe he'll change his mind.
