IFlyRC - The build tent(s) will have 120 V A/C to plug into. Crafty Dan is the man who will bring the power to the masses. (Dan, do you know if FT is planning on renting a mega-generator? How about that mobile wifi we talked about last year?).
Fortunately, (or unfortunately from my wife's point of view) YES, there will be vendors selling all manner of components, kits, ARFs and RTFs at pretty darn good prices. Last year, I marveled at the good deals on components from Lazertoyz and others on a daily basis. Man did those good deals add up fast! LOL!!!
I would bet there will be even more vendors on-site this year. Competition is always good for the consumer.
