I only really care about Indie, Nintendo, Sega, Bethesda and Valve games. Those are pretty much the only video games I play anymore. And when I say Bethesda, I mean Elder Scrolls and New Vegas, and nothing else they do (not even Fallout 4 excited me).
Nintendo is usually the only part of E3 I care about, generally. This year, days of Zelda coverage will be kind of nice I guess, but the game is so far away, it hardly seems worth it to get excited for it. It's not really like Smash Bros where I can get hyped for literally years and never get tired of it, since it has no story and basically limitless game play.
So this year will likely be the first year in about a decade where I don't really actively follow E3 or get excited for it. I am entirely out of touch with modern gaming (especially western games) and have very little interest to get into it at all.
