Update: As vaguely suspected, it's a hoax after all. A slightly boring hoax. Well done, boring hoaxers.
Surprise! I've just broken into your house and stolen all your milk. No, that's not the real surprise. The real surprise is that there's going to be another Call of Duty game this year. No, that's not a surprise either. The real surprise is that it sounds like we might see a bit of said game at GDC next week. At least, that's according to a new web intersite called FindMakarov. Makarov is, you may recall, one of the baddies in Modern Warfare 2, as well as That Guy, Him and Wossiface.
This is all according to That Videogame Blog, which is claiming to have received some fake blood-smeared dogtags from Activision with the URL in question stamped on them. Haven't heard of anyone else coming out of the woodwork as having these tags as yet, plus there's no mention of Activision or any of their studios on the page source or via a domain lookup. - let's go with it for now though. It seems real enough.
On the mystery site is an incredibly annoying, repetitive noise, and a timer suggesting something's going to happen in just under 5 days. Why, that's just next week!
Hopefully it'll be online as well as on show at GDC, so we can all join in. So will this be Infinity Ward again, or at least what's left of them, or the new 'Beachead' studio Activision has set up specifically to handle future Call of Duty projects? MYSTERIES.
