E3 likes to position itself as the 
launch point for the future of gaming.
Already this week, Nintendo has unveiled Wii U, its next generation console; Sony has shown off its new portable device (dubbed PlayStation Vita) and the big games of holiday 2011 — and, in some cases, 2012 — are on display.
But while console and dedicated handheld systems are well represented here — and games for mobile phones have a moderate presence — there are very few social network gaming companies at the show. And given the growing size of that segment of the industry, that’s a major hole.
