For Sony's TGS I'm thinking
Freedom Wars 2 for PS4/Vita
God Eater 3 for PS4/Vita
Yakuza 6 for PS4/PS3
New Hatsune Miku for PS4/Vita
Valkyria Chronicles IV for PS4/Vita (SEGA's major console game announcement)
Possibly Ni No Kuni 2 but this might be announced at a Western show given the popularity over here
Gravity Daze 2 for PS4 but I think this will also be at a Western show
And new trailers for DQXI, DQB, DQHII, Persona 5, Hot Shots Gold PS4, Ys 8
And my "out there" predictions would be
Final Fantasy X-3
Monster Hunter Musou
Resident Evil 7
Both God Eater and Freedom Wars are made by the same dev, who are also working on God Eater: Resurrection, which releases this holiday, so I doubt they'll have GE3 and FW2.
The Yakuza team has been confirmed to be working on a non Yakuza game, so probably no Yakuza 6. This is also predicted to be SEGA's major console game.
