Couple scans have surfaced from the latest famitsu where we get, for the first time, an official confirmation that Rose is indeed in Street Fighter IV.
The scan shows ingame screenshots of Rose and Gen as well as an ikeno Art of the lady in red.
The scans also confirm that Gen has indeed two fighting styles like it was hinted few weeks ago.
Unfortunately the scans are really Low quality, but rest assured im hunting for so high rez version and i shall post them as soon as i find them.
