Final Fantasy 15 may not have the presence you were expecting at E3 2015.
According to game director Hajime Tabata, Final Fantasy 15 will not start the next phase in its marketing campaign at E3 this year, but rather at gamescom.
In the recent Active Time Report (as translated by DualShockers), Tabata said that E3 being so close, won't give the team enough time to prepare for what they want to show.
Gamescom is where we'll most likely get new Final Fantasy 15 information.
Square Enix will host its own conference at E3 this year, so we may see a new trailer for the game still. Between E3 and the release of Episode Duscae 2.0 in May, Tabata will reveal more information about the survey he mentioned today.
