We need an OTcon.
All of us in one place would be a good way for Lucasfilm to track all of us down and confiscate our non-sanctioned versions of the movies. It would be a day long remembered.
However, I may muster the courage to go to Celebration next year. Maybe.
I worry what I may see there (EU/PT fanboys), but cherish the possibility to be around for some huge announcement (OOT release, VII details, 3D, whatever.) If I go, I will definitely be representing the Holy Trilogy all the way.
e.g., watch a few fanedits and a few preservations on a big screen; attend a talk by Adywan|Harmy|Poita|Team_Negative1; attend an Adobe AfterEffects speed-tutorial; count petition signatures with pat man; check out booths publicizing new fanedits and preservations; meet TV's Frink; be a part of a short movie documenting the convention; <insert your idea here>.
Ah, no! You are getting my hopes up only to be surely crushed!
