Yup, finally we get an announced date after so long.
For your long days of actually trying to find a copy of this game is over. =P You can simply download this game on August 23rd for PSN and August 24th for XBL. And in case you didn't know, it has online. And since it's Capcom, expect DLC as well.
So yeah, screw SSFIV AE, this is much worth it.
