The math is right...
Yesterday, there have been reports of Star Wars games for the PlayStation 2 have been running on the PlayStation 4 through emulation. Wired contacted Sony and they've confirmed that the reports have been true.
The report mentions, Star Wars games from the PlayStation 2 has been included in Star Wars: Battlefront for the PlayStation 4 as a selection of bonus "classics."
With such great news, we expect to have an expanded library of classic PlayStation 2 games on our PlayStation 4 consoles soon.
