I don't expect Versus XIII or XII Agito to show at E3 this year. It's be KH:Birth by Sleep, KH3, Final Fantasy XIV, 3 tons of crap and a Final Fantasy stapled on sequel for one of the other games... maybe even another VII one... I'm loosing faith in Square-Enix even more these days. I blame the merger for all the mistakes and poorer quality of games they have make since 2004.
I say ignore Square-Enix this year and look at Mistwalker's The Last Story for this E3... assuming it's there.
