The PlayStation Blogcast mentions a "buffet" of demos are coming to PlayStation Network. PlayStation 3 users will be able to download demos of Final Fantasy XIII-2, Grand Slam Tennis 2, Under Siege, Wanted Corp, and Asura’s Wrath.
Capcom announced the Asura’s Wrath demo in Japan, which includes two stages from the E3 and Tokyo Game Show demos. Details about content in the Final Fantasy XIII-2 demo have not been announced.
A tip of the hat for James for the heads up!
