Yes and this event is labeled as WonderCon Anaheim so it looks like this one is here to stay
Yep...this is what I predicted when they first announced they were moving Sept. 2011.
I totally concur. WonderCon is unquestionably a few steps below SDCC with programming, guests, vendors, etc. However, it's steps ahead of pretty much all the other cons. So a third mainstream con by CCI would likely be spreading it pretty thin to a point where it would likely be a step or two below WonderCon. At that point, it might as well be a Wizard World or similar. I'd still go because I'm a fan, but I think you'd have to be realistic of your expectations.
There are a few that are gaining fast, though. NYCC (only started in 2006), Emerald City ComiCon, and Phoenix ComiCon come to mind. If CCI has the resources to pull off three, the demand is there.
A big difference between CCI & WizardWorld is that CCI already has the brand & plenty of competent events under its belt. WizardWorld got in over its head before they started.
Now I do see a scenario if they timed it out strategically, maybe there's hope. If they put it just before the Thanksgiving rush, I could see there being guests/panels that cover the movies that come out during that popular time like Hunger Games and Hobbit, even Wreck It Ralph and Twilight (sorry) got released during that stretch. I could also see maybe some vendors showing up to capitalize on the holiday spending. Hmmm...maybe it could work?! Late October or early November? 
Yes, a fall (or even winter) con would be good. Most of them seem to be in the summer or spring.
I'd rather WonderCon just come back to Moscone though!
Ditto. Or have a major one in SD, Anaheim, AND SF.
That's the real trick, right: when to put the "new" Con. When is APE? Is APE different enough to not clash with a WonderCon North?
APE is in the fall. It could be combined with a "WonderCon North" and CCI could possibly gear that more towards the comics underground. I could see that working pretty well actually.
I personally think WonderCon doesn't need to necessarily cater to Hollywood. It's OK if WonderCon is mostly comics with some movie & TV panels, but I think there's nothing wrong with WonderCon not have a star-studded, lots-of-Hollywood-panels/presence line-up. Leave Comic-Con to cater to all aspects of pop-culture, & WonderCon can be it's own thing.
Too late; WC is about five years behind CC and it looks like they, too, want to keep on getting bigger. I also suspect one of the reasons they moved south is so they could be closer to the studios. (And if they do stay in Anaheim, I'm all for them filling up the convention center...anything that will prevent them from being held at the same time as a volleyball con.
