Damn Sega lol
It's nice of them to acknowledge the game when we talk about it, but it's hard to not think that there is a hidden meaning with them. The way I see it, the dude sitting on the other end of the twitter account probably just wants to reply to people, hell, he might even like Shenmue, but in reality he probably doesn't know much about the behind the scenes of Sega and their unreleased projects.
Everything I see, and everything that I feel makes me believe that they will re-release them before S3 but yet again... ITS SEGA! I'll believe it when I see it...(and I'll keep on wishing and getting my hopes up when they Tweet about it).
