SEGA has launched a new Japanese teaser website for an impending PlayStation 3 and Vita project, but additional details are being kept under wraps. The page – which features some kind of dust effect – hints that all will be revealed on 28th March. Why do we have to wait so long?

Unsurprisingly, speculation regarding the secretive project is rife. The most common suggestions point to new entries in the Yakuza and Valkyria Chronicles franchises. The former seems unlikely, however, seeing as creator Toshihiro Nagoshi recently hinted that the next entry in his gangster series would be on the PlayStation 4.

We’re stumped. Let us know what you think the game could be in the comments section below.
