While Wedneday brought the rumor that 2010 Comic-Con International's Preview Night would move up from Wednesday to Tuesday here in San Diego, today comes the rumor that the convention might be leaving San Diego altogether.

Word is going around that the popular entertainment world will descend on Los Angeles next year, leaving the San Diego Convention Center behind.

It's not the first time this possibility has been raised, but the sheer and ever-growing size of the convention is making it look more likely.

The movie studios and TV networks run Comic-Con now, and they'd rather schlep their mega-displays, merchandise and stars across town in LA than down the I-5 to San Diego. And, the LA Convention Center is big enough to take the Comic-Con load.

But, factors in San Diego's favor include ample nearby hotel space and an adjacent Gaslamp Quarter providing plenty of places to eat and party. While downtown LA has been coming back in recent years, you're still more likely to be accosted than well-fed around that convention center.

Since the word is out, you can assume the San Diego city reps will go to war to save this massive boon to San Diego's summer economy. And, LA-weary showbiz types like coming down here.

TV Squad is rooting for you, San Diego.
