They've openly been saying since before E3 that Gamescom marks the start of the official promotion of the game right up until launch and is 100% why they didn't show it at E3. FFXV is their big ticket item at Gamescom. There will be something new, especially as TGS or Jump Festa is when they've said will see more about FFVII HD. D23 later in August is when they've said more of KHIII is going to be shown off.

Gamescom will be where they come out with all guns blazing about FFXV.

They have the likes of Tabata attending Gamescom. They're doing an Active Time Report at Gamescom.

SE may have been many things in the past, but they certainly haven't been dumb with information concerning XV since Tabata took the reigns.
