Every wondered why Superman has such disdain for Lex Luthor? Well, it's because Lex refused to show up in a very pivotal time in his life where he was ready to ascend from Clark the Blur to Superman. Posted three days ago (The 14th of January) via his Twitter account, Rosenbaum denied the rumors of any talks between himself and the Smallville producers....

Michael Rosenbaum
Honestly don't know where people get their information from,but i haven't discussed Smallville with Producers or anyone in quite some time.
There you have it, Rosenbaum is still shafting us on Lex Luthor.
