E3 2017: All major announcements from Microsoft, Sony, Nintendo, and more

E3 2017 officially kicks off today, but from here on out, big announcements will likely be few and far between. Like every E3 in recent years, major game companies have opted to host press conferences before the event begins, which is where they make all of their big announcements. There were six big press conferences of note this year – Microsoft, Sony, Nintendo, Electronic Arts, Ubisoft, and Bethesda – and what follows are the biggest announcements from each of them.

Microsoft got Sunday going with a bang. Perhaps the biggest press conference of the show, Microsoft delivered all sorts of details on Project Scorpio, which was revealed to be the Xbox One X. We learned more about the console's internal hardware before Microsoft announced that the Xbox One X will launch on November 7, 2017 with a $500 price tag.

Xbox boss Phil Spencer also revealed 42 games that will be optimized for the Xbox One X, with 22 of those being exclusive to the Xbox One brand in one way or another. It was during this show that we got our first in-depth look at games like Assassin's Creed Origins, Anthem, and Forza Motorsport 7. The Xbox One X makes a bunch of big promises about 4K gaming at 60 frames per second, so we'll see if it can deliver later this year.

Ubisoft, normally the king of cringe, actually had a pretty surprisingly stellar show. The show started with none other than Shigeru Miyamoto taking the stage to help Ubisoft introduce Mario + Rabbids: Kingdom Battle for Nintendo Switch. Yes, that rumored Mario and Rabbids mash-up does indeed exist, but in a form none of us expected: as a tactical RPG that seems to share a lot of similarities with XCOM.

During Ubisoft's show, we saw some good looking footage from both Assassin's Creed Origins and Far Cry 5. The company also announced a new pirate game called Skulls and Bones, but the biggest surprise didn't come until the very end of the show. It was then that Ubisoft finally revealed Beyond Good and Evil 2, a game fans have been waiting more than a decade for.

With the Switch just out of the gate and Nintendo needing to give people a reason to buy, this was a big show. Nintendo took advantage of that by announcing a bunch of new games for the Switch. We'll see Kirby and Yoshi star in their own games for the Switch next year, but they won't be alone – Nintendo also revealed Metroid Prime 4, though we didn't actually get to see any footage from the game.

Nintendo dropped a bombshell of an announcement about halfway through its livestream, revealing that a core Pokemon RPG is in the works for the Switch. Finally, it wrapped up the show by announcing that Super Mario Odyssey will launch on October 27, 2017, a lot earlier than some were expecting.
