This E3 will be important for Xbox, and in a recent interview with Xbox On (shared by Gamespot moderator charizard1605 on the Gamespot forums) Xbox chief Phil Spencer said that he was feeling optimistic about what they have to show.
"I think the game line-up this year across the board is fantastic [...] and I think Scorpio will be the best console to go play these games on," he said. "I've had some opportunity to look at some of the third party games, which are coming together so well. I'm obviously playing our first party games. And I think the creativity and diversity this year is fantastic. Something like Destiny 2 is coming, I was over at Bungie two weeks ago, and I got to play a little bit, and it got me back into the first game."
"But I think the games that are coming out, the new Star Wars game, Red Dead, some other stuff that's not announced yet, the new Mordor game... It's going to be a great year and a great E3."
As you might've noticed, Spencer doesn't talk about any first party games here, but let's hope this changes at E3. What do you hope to see from Xbox?
