Destructoid is reporting that Valve has confirmed new models for all special infected appearing in L4D2. Series writer Chet Faliszek is quoted as saying

"One of the weird things with Left 4 Dead 2 is that we're not showing a finished product, yet it plays like a finished product, so all those guys are getting re-skinned and remodeled," Chet answers. "They're going to be mutated to the area -- it's the South, it's a little hotter. A guy running around in a hoodie is gonna be a little rare. We haven't shown that yet, we're gonna be showing it ... actually I don't know when we're going to show it, but it'll be shown before release."

Someone tell Thanksgiving we've got another reason to be excited for November, L4D2 is going to be serious business. We can't wait to see what the remodels look like....with their heads blown off.
