Well... it got me pumped up.
Was his v-trigger a dash cancel? Looked really cool.
I do hope that they get a classic Ken outfit for Ryu just for old times sake though. The current outfit is silly (and hairstyle), something that can be solved with a different outfit aswell.
And to answer the OP... there were actually rumors that Ken wasnt going to make the cut, so this was definitly a relief for Ken fans.
