Eurogamer says they've been informed by Atari that a reported delay of Alone in the Dark until September is simply a rumor, but the company wouldn't take the next step and say the game will release as expected in March. Yeah, that's just a bit awkward.
If you're having déjà vu about Alone in the Dark delay issues, it's probably because Atari went through this recently with an AitD delay rumor on the PS3. If there's any questions about AitD coming out in March, it's worth noting that IGN wasn't given hands-on time when it did a preview on the game last August. It's only a matter of time before we use "delayed" and Alone in the Dark in the same post again.
