LOL, great post, was just typing the same thing but I'm glad I scrolled down, IMO your posts today have been right on the money.
DNAD attended last year and subsequently landed some nice contracts, if they are up to their necks in development work for the year than they need to focus on what they currently have. They are a startup that's strapped for cash, if there is not a great reason for them to exhibit then I'd rather they not.
I wouldn't be surprised if they attend E3 however, that's all DNAD really needs to do at this juncture.
It's a long shot, but with the currently unannounced projects they are working on, maybe they'll just be hanging out with companies already exhibiting at the show and be involved in their booth(s)....
