By the time E3 2017 rolled around, Nintendo Switch was barely three months old. Coming off the success of The Legend of Zelda: Breath of the Wild, what other exciting things were planned for year one of Nintendo's newest system? Going into E3, the company had the wind at its back, but it still had a lot to prove.

Sony spent an hour of its June 13 conference making use of its stage to put on a theatrical performance. Hanging corpses and pyrotechnics dazzled (if you're into that sort of thing) for a presentation that was light on industry buzzwords, relied heavily on a trailer showcase, and had very few new announcements.

E3 fast approaches, and you know what that means: New game announcements and all the gaming news you can handle are headed our way. It also means it's time to rewind to 2017, when the three console makers made a plethora of promises during last year's E3 festivities. Did they keep them? Let's find out. First up: Microsoft.

Nintendo doesn't play E3 by the same rules as its rivals, but its E3 2016 showing was its most radical departure from the formula ever. Its booth featured a single game, The Legend of Zelda: Breath of the Wild, and it replaced its big pre-recorded digital event with a series of livestreams that ran throughout E3 week. But it still had some announcements and promises, which it mostly delivered on.

To what lengths do you go to introduce the return of one of your biggest franchises? If it's for God of War, you bust out a full orchestra. Sony's E3 2016 press conference began with a spectacle -- but impressive showpieces aside, did the company meet its E3 2016 promises? Let's find out.

E3 is right around the corner, and that means we're about to get deluged with colossal news and shiny new trailers. And as we do every year before the hype, let's first take a look back to see if the three console makers delivered on all the grand promises they made at last year's E3. Up first: Microsoft.

Nintendo's digital events have become a highlight of E3 -- pre-recorded presentations, as opposed to live stage shows, that are full of fun and filled purely with games. There's no planned Direct this year, but let's see if they kept their 2015 promises.
