Despite the ongoing slow demise of print media, the cover of the monthly Game Informer magazine remains a popular ad slot for games publishers, owed largely to its wide free circulation in North American retailers. According to tweets from GI's Andy McNamara, tomorrow's reveal of the April edition front page will be one to look out for, as the editor teased "it's a next gen game I'm personally thrilled to get to reveal.", and further explained that it's not Assassin's Creed IV, which has now already been formally announced by Ubisoft.

The always-resourceful crowd over at NeoGAF seem to have found a couple of other pieces to the puzzle, corroborating a previous mention from Game Informer that the next cover "contains a bow", with this post from an Eidos community manager hinting at having something new to share tomorrow.

*ahem* What's this??

You guys are talking about Deus Ex in the Thief forums??

This won't do. Not at all.

I'm gonna have to do something about this.............. Something drastic.

Lets reconvene tomorrow. Set your watches, taffers.

The obvious conclusion of course, being the long-awaited Thief 4. However, McNamara has since followed up with another tweet promising that "tomorrow's cover does not have a 4 or IV on it.", rousing speculation that the game could simply be called Thief.

Originally announced under the tacky moniker THI4F, the stealth action sequel has long been in the works at the Square Enix-owned, Canadian studio Eidos Montreal.
