As suspected, Microsoft has now confirmed that it will reveal new IP during its briefing at E3 next month. Xbox boss Phil Spencer revealed the news on Twitter, bluntly stating, "We will have new IP at E3."
He didn't share any further specifics. Last month, Spencer sounded unsure about Microsoft's new IP plans for E3, as he said that Microsoft "should have new exclusive IP at E3."
Also on Twitter, Spencer shared that Microsoft will talk about more than just games during its E3 briefing. "There are some platform features we'll want to talk about," he said. He didn't go into specifics.
Finally, Spencer addressed the fact that Microsoft will be the first of the Big Three (Microsoft, Sony, and Nintendo) to hold its briefing this year. He's not worried about going first.
"We set our tone and show," he said. "Others can react if they want to, but I'm comfortable being the first platform briefing."
As announced yesterday, Microsoft's E3 2015 briefing is scheduled for 9:30 AM PDT on Monday, June 15. GameSpot will bring you all the news as it's announced.
