An interesting marriage of ideas is to employ girl gaming clans as "totty with triggers" -- a booth attraction that appeals on multiple levels. Arguably, that's what Ubisoft's "Frag Dolls" team is all about, but the Dolls won't be alone at E3 this year. g0d (girlz of destruction) will be bringing their VIA-sponsored "home of chrome" to the show floor, and the PMS clan will also be sending members to E3 to work for various sponsors.
There is a difference between groups which were set up specifically by one company, or which formed in order to seek sponsorship, and those which came together naturally -- though on the show floor, that's less apparent. Clans like g0d and PMS are becoming famous, and attracting sponsorship now, but they formed for fellowship rather than financial gain. With professional gamers in general getting more exposure these days, it seems that the gender of all-girl gaming teams makes them an immediate hot prospect to replace the stereotypical eye-candy booth babes.
