I plan to go. Probably later on Friday or Saturday.
Per my dealer, AOA may have these: Q7, TTS, R8 (V12 is not confirmed yet). New A4 is doubtful. I should get a call with an update closer to the show date.
Xplod.... will do. I may try to get down there Wed or Thur to beat the crowds.
Looking at the floor plan at the DC Convention Center Show, as depicted in the Wash. Post, the Audi booth looks a little on the smallish side. Somewhat comparable to BMW and VW, but not as small as Mini and Porsche.
I suspect that may limit what Audi can bring.
