Avowing their "every intention of letting [fans] be the first to know the reality," Smallville executive producers Brian Peterson and Kelly Souders have issued a statement addressing rampant speculation that the development of The Graysons, a new CW series chronicling the pre-Batman days of young master Dick, means that Clark Kent's own days are numbered.

"Never have we been so committed to the continuing success of Smallville as we are to seasons 8 and 9," the pair say in a note posted to KryptonSite.com. "While we are extremely excited to... create the origin story of Dick Grayson, it has never been intended as a replacement for Smallville."

Souders and Petersen, who are creating The Graysons with Supernatural executive producer McG, go on to promise Smallville fans, "[We] are all working full-steam ahead on a storyline for Clark that allows for seasons of further trials and adventures for our favorite hero." — Matt Mitovich

I've been a fan of Smallville from the start ... but how much longer can
they delay the inevitable day when Clark becomes Superman? Tom Welling is
already older than Christopher Reeve was when he was cast as Superman! :lol:

i think that they have already changed the Superman mythos enough that they could make Smallville keep going for a lot longer - Smallville's Clark Kent is no Superboy, surely they can continue the same path even though he has moved to Metropolis...

I think they need to work harder at bringing in new villains for him, more like they did in the first few seasons where it wasn't all about Clark vs Lex.
