Oh dear. Microsoft has accidentally listed details of its biggest E3 announcements, including Halo: Anniversary Edition and Halo 4.
As you can see from the image on this page, Xbox.com briefly listed the pair of new Halo titles, Dance Central 2, Kinect Sports Season 2, Kinect Fun Labs and a Kinect title called 'Ryse'.
"The news millions of Halo fans have waited for: Halo 4 is on the way. But that's not all..." read the official Xbox site, before the listings were pulled.
Halo: Combat Evolved Anniversary Edition - which has been rumoured for months - is described as "the epic game that launched a universe, remastered for a new generation".
Kinect Sports Season 2 looks set to feature baseball, golf, skiing and tennis. The page also confirms new features for Xbox Live, including voice search.
Somebody's going to get shouted at. Check back from 5pm BST to see this stuff officially confirmed.
