But what's interesting about some of the art is that they appear to be images that have not been seen before. The trooper has been seen before but facing in a different direction. Darth Malgus in the background also appears to be from the 'Deceived' trailer'. But the rest . . .
The Jedi in the center Master is Ven Zallow also from 'Deceived' but in a different stance. In the background we have the Grand Master Satele Shan from 'Hope' and 'Return' but holding her blade in a position not seen in those trailers.
In conclusion this is an incredible fake until validated by BioWare. We have to give the creator credit for this amazing art work.
