SEGA’s Twitter has recently posted a mystery image on Flickr, seen here, of a forest setting with a chunk missing from the image and a question mark. Clearly they are teasing a new game, but what game could it be? Well, we shared the initial image on our Facebook page, and a kind reader by the name of Marius Theßeling speculated that the art matched the style of Ron Gilbert’s unannounced upcoming game from Double Fine Productions. And sure enough, it matches up! We simply grabbed the image from SEGA’s flicker, and dropped in all the character art from Gilbert’s blog onto the image. Just like a puzzle, an image came together and you can see the completed image above. So it’s official: SEGA is teaming with Double Fine to publish a game! Sorry if we ruined the surprise, SEGA. But all the pieces were there.

[First scan/concept art of the upcoming game]
Yuji Naka’s upcoming game has been teased in Famitsu and it won’t be published by SEGA. The game will be published by Kadokawa Games. Never heard of them? I don’t blame you, all they have done was a port of RPG Maker for DS and some other girl anime game. But it seems the company wants to become bigger, first step is with the Yuji Naka HD game (along with a game by Grasshopper).
“The game itself is an action title that takes place in the sky. The action gameplay is what I’m focusing on the most with this project — interactivity is the most important attraction with any sort of game, and if that doesn’t evolve, then games won’t be everything they can be. Sonic was all about completely taking over the land, and Nights brought that same concept into the skies. I had always thought that action games that take place in the sky are too hard for players to cope with, but then I thought up a new method for dealing with it. That’s how this project got started. If I had stuck around at Sega, then I might have used this concept to make a sequel to Nights!” - Yuji Naka (Prope)
It is most likely that SEGA passed on publishing Yuji Naka’s title. Most likely due to how poor a bigger known IP like NiGHTS did on Wii and how he compares the concept to that or it could be due to how poor Let’s Tap did. We will never know. We wish Naka luck with his new title and if its good, of course we will all be playing it, regardless of publisher.

Their countdown site is titled “next-360action”, assuming the game will be an action game exclusive to the Xbox 360. Maybe its Yakuza series coming to the platform?
Who knows, I guess we can all sit down and throw some guesses out there. Check the site, right here. SEGA is suppose to be dropping hints via their twitter. Assuming its their Japanese account.
