There's definitely been a steep drop in the amount of booth babes over the past few years at GDC, and the lone holdout seems to be N-Gage. They have a lot of silver jumpsuit-clad babes, complete with space-age utility belts around their waists, urging people to come into their mobile space. One girl was actually clapping loudly to try and lure in the shuffling hordes of developers, not to much avail.
We still salute you, oh valiant babes of the booth. In a very non-sexist manner.
