A trailer isn't any reassurance that he'll be more prominent in the Remake, and even if it was, there's still tons of time to release a trailer before launch.Except that one of the main playable characters of the game hasn't even been officially mentioned yet, not a hint said or shown of him. They haven't confirmed that he'll even be in this part, and I should think they would show all the playable characters by the time of the game's launch. Considering how they treated Red in the Compilation, I'd have thought you'd want a bit more reassurance that the same thing isn't being done to him here.
I think the venue plays an important role too. The Game Awards has a really broad reach--it's not just for FF nerds online--so a trailer with your badass sword swinging protagonist fits. Something like Jump Festa later in the month seems like a much better time to release a Red XIII trailer.
