The big Microsoft E3 press conference airs tonight and so the Gamerscore Blog crew took a few pictures of the venue (a high school) where all the fun will be going down later and posted them to their Flickr account. But they obviously posted photos that they shouldn't have and quickly pulled a bunch of pictures featuring the venue and the rehearsal. But Joystiq reader Rickard Gudbrand was quick to take a screenshot of the one gray Xbox image (but we found a higher res one here) before it was pulled. Indeed, it is a gray 360.
So, what does this gray Xbox 360 mean? Well, we aren't sure and will have to probably wait until the press conference later tonight, but we'll go out on a limb and say it may have to do with either a price cut or be a reworking of what the Core system offers. Microsoft ... always wanting to surprise as if it were Christmas in July.
Update 1: We've stumbled upon a higher resolution version of the leaked photo. Enjoy.
