Nope - it ain't what you think it is. Star Wars Celebration V has not yet been officially announced (*sigh*).
But Steve Sansweet did speak briefly with Bryan Young from Examiner.com at this weekend's Dragon-Con about this very subject and why we have not yet had any concrete details released on the convention.
Here are the main highlights from the conversation:
1. Celebration V will take place next summer (2010) to commemorate the 30th anniversary of The Empire Strikes Back.
2. No Place or time has been set, though there are two things Sansweet said this weekend to remember:
A) They've inked deals like this as late as 6 months out, and: B) It will be on the "right half of the country" (which, according to Sansweet, means that it will be somewhere between Chicago and the Atlantic.)
Nothing we haven't heard/speculated on many times before (save for the 6 month out bit).
