Ryse 2 being shown, Lionhead's second project, Samaritan exclusive to Xbox One, games by Rare, Good Science, LXP, and "Platform Next Games", specifics about Platinum's game and titles of the next Gears and Crackdown games are not what I would call safe predictions.
Ryse 2: Rumours very early on after X1 launch which pointed to it being in development.
Lionhead: http://www.eurogamer.net/articles/2...is-working-on-something-that-isnt-fable-esque
Rare: People have been screaming for them to make something non-kinect. Finished KSR and are a very large company, logic says they're working on another game. MS even answered questions in an interview around their Kinect games.
Good Science: Not heard of the studio personally but makes perfect sense for a game to use Kinect in this degree, they did include it in the box and the concept sounds intriguing but definitely possible.
LXP: Studio owned by MS but not shown anything, logic points to a game.
Platform Next Games: MS have been very outward in communication about setting up and acquiring studios.
Next Gears: Was announced when new IP was purchased, people will be expecting at least a CGI trailer for the direction considering the following the franchise has.
Platinum Games: We've heard for ages some big JRPG's are on the way.
Crackdown: Remember the icon on the reveal? People have been asking and Phil said he'd love to see one.
Epic: Always had a strong relationship with MS (Gears of War). With selling the IP to gears and with the size of the team they have, they have to be producing something.
For me you could come to those points logically but they are very out there and wet-dreamish. We all can hope!
