While I do agree that TGS makes a lot of sense for a Japanese game, I still think it's more likely to be reintroduced at a western event to try and sell the game to Western gamers. For instance, it would have made a lot of sense to introduce Bloodborne at TGS, but it was formally announced at E3 instead.
However, the guy from Famitsu did tease a big PS4 announcement for TGS...
