Eh, even when Nintendo "quit" E3, that only meant they went from a stage show to their Directs. As far as I can remember they've continued to have a floor presence at the show. But, yeah, E3 has been less and less of a real "event" for a number of reasons over the years. Something I've noticed the past few times is that almost no one actually has their stage show during E3's official time period. Their always basically "satellite" events taking place in the week leading up to the convention. Oddly enough, Nintendo's digital presentations are one of the few that happened during E3 (usually on the first day, as I recall). And of course some major players (most recently, and probably most notably, Sony) have skipped E3 entirely the past couple times.
