They have already announced a new information for KH3 coming this winter so don't expect news at TGS :(
as for Final Fantasy 7R is the same thing I don't think they will talk about it at TGS because of FF15, they want all the focus on FF15 before they move to KH3 and FF7R.
I want to see more of Ni No Kuni 2, and I want to believe that sony is making JRPG :)
