I find it doubtful. It has been announced that the game will venture into TLJ, and with DICE's attention to detail, trying to get their ingame models as close as possible to the used props. I think we can safely assume that this helmet will be a good representation of what we will see in TLJ. Worth noting is that the fore-arms are in the TFA style.
I am assuming that they have been working on a trooper model before the new TLJ redesign, and that they have recently updated their helmet to represent the new movie.
Ofcourse, we wont know it for 100% certainty untill more movie footage.
