Xbox boss Phil Spencer announced plans for a new Xbox console on the Xbox E3 2018 stage. He didn't share any specifics, so some wondered why he made the announcement at all. Speaking to GameSpot sister site Giant Bomb, Spencer said he did so to assure people that consoles remain important to Microsoft as a company.

"Anybody who might worry about our console future, I just wanted to put that at ease," Spencer said. "I wanted people to know that I love the track record of our hardware team ... we have some ideas in the future [about streaming] but it's not tomorrow. I didn't want people to think we were going to walk away from that part of the brand in the business because it's really important to us."
