Yeah, the timing is really weird. Maybe they wanted to push this character forward so they can reveal Balrog during GamesCom lol.
I think its like this you know how ken had a while thing because he represented the retooling of characters and a visually different design and a bunch of new varients in his movesets.
Vega in that trailer looked like vega in sf5 he just had his sf4 alt on. Why waste anyone's time at gamescon with that reveal, you kno what vega is about. Shennanigans. There were some new crazy diagonal air moves, but it was ike " yep... vega "
