Interesting stuff. Dissidia on PSP was quite a popular game amongst my friends so looking forward to seeing how this pans out.

I hope it will come to vita too

... this the secret game to be revealed the 13th by SquEnix? Or is that a SquEnix-Eidos thing?

No, they had a Dissidia Final Fantasy Conference today, this is separate.

Uhh... Team Ninja developing? What?

I can't wait! This is like a dream come true.

Then thumbs up. It's sad that the last japanese made SquEnix game I bought was FF13 (only other SquEnix game bought last gen was Deus Ex) when pretty much my main games back in PS1 and PS2 era were Square or SquEnix made.

Awesome to hear, I played a little bit of the PSP games but never really gave them a bunch of time thanks to other games I was playing at the time. Will happily jump on board for a new one on PS4

Oh, man. I am VERY excited for this to hit the proper PS4 and get localised.
