Xbox chief Phil Spencer indicated in an interview with Digital Trends that E3 2018 will see some "positive changes" this year. No word yet exactly what these changes will be, but Microsoft likely wants to avoid the issues they faced last year at E3 2017. E3 2018 will take place in Los Angeles, CA on June 12-14, 2018.
Looking to the interview, Microsoft's Phil Spencer indicated some changes coming for E3 2018:
“I don’t think we’ve talked about [it] yet, but I think will be some positive changes at E3. Could be fun for us; it’ll be a nice change.”
Nothing like a vague statement by Microsoft to put the Xbox world in a talespin. Various rumors have been going around, namely a possible Halo 6 in the works. Other rumors include another Gears of War (5), and a possible Fable 4.
