Considering the armor would've been animated as flawlessly as the one in the trailer, the helmet would be missing (as it always is for main characters of the trailers), and he would've pulled off the same amazing feats: Yes, just as many people would've played the game.
Personally, I like the design because it just screams 'intimidating' more than a black robe... So playing a Light Sided Sith in that armor is even funnier than it already is usually!
