E3 2015. In that event we saw three megatons: Square Enix revealed Final Fantasy VII Remake, Sony re-announce The Last Guardian for PS4 and Yu Suzuki came back from the dead to unveil Shenmue III alongside a KickStarter campaign to finance it. E3 of dreams.
The dream could continue if the following info becomes something tangible. Sega Europe has registered Shenmuehd.com domain. Sega could be evaluating to produce a series of remasters for Shenmue I & II or this movement could be just a commercial measure to cover possible projects based on their IPs.
We will see, but I hope this will be sooner than later.
