It looks like Microsoft are set to host a press conference at Gamescom, which opens up in Cologne, Germany next month. This would mark the first time the Redmond giant has held a press conference at Gamescom since 2005.
CVG are behind the report, citing unnamed sources who have said that "organizers and third party" studios have spoke of the plans of a one-hour long conference based around the Xbox One. Back in May of this year, Xbox EMEA Social Marketing Manager, Graeme Boyd, tweeted: "Xbox will be back at Gamescom this August. Next chapter of Xbox gaming experiences on show."
Microsoft in the UK have released a statement to CVG, where they said: "We're excited to be back at Gamescom this year but we're not announcing any further details on our plans at this time. Please stay tuned for more details."
