First of all, I must tip my hat in Sony and Microsoft's general direction for their great job of integrating E3 into their Live and PSN services. It was great being able to download demos, trailers and more the moment they were announced at E3. Really, a great feature. Shame on Nintendo for not doing this, but they don't really care.
