This E3 isn't even over yet, but there are plenty of outlets asking whether the new format is a success or failure. Today a British television outlet was sitting other Brit journalists down (it's so Metabrit) at the Viceroy hotel and asking them what they think about the new E3.
Certain things said were that it's like a film festival and one outspoken member said, "Nintendo had a tough time the other day because there wasn't that fanboy element." The fanboy comment had actually shown up in numerous elevator rides and hikes from hotel to hotel while listening to other people's conversations. The one clear thing is that the lack of fanboys would explain the lack of schwag -- it's like a desert here, and we wanted to give it away at our Reader Meetup.
