Flaregames' communications chief Gunnar Lott may have dropped a major hint as to what to expect from Microsoft's upcoming Xbox One Indie announcement, expected to be discussed during the firm's Gamescom showcase event tomorrow.

Speaking during Microsoft's GDC Europe talk, "Be what's next - Microsoft's commitment to Indie success", Lott claimed that he had heard Microsoft's Windows Store - the app store used on Windows 8 and Windows Phone 8 - may be coming to Xbox One.

But when asked about the subject again later in the talk, Microsoft technical evangelist Kristina Rothe chose not to confirm or deny the rumour, claiming that she didn't know.

"Let's wait for the coming announcements," she said. "It's going to be great I can only assume because obviously this whole cross-platform thing is really important, but I don't know anything unfortunately.

"Even if I did," she joked, "I couldn't tell you without having to kill you all."

Rothe added that she believed an announcement regarding Indie development on Xbox One was due this week.

Flaregames previously released Royal Revolt on Windows 8 and Windows Phone 8, alongside other mobile platforms.

Microsoft revealed plans to allow self-publishing on Xbox One last month. More details are promised for Gamescom.
