358/2 Days Sudden Theory On 14th Member

Good theory, I didn't know there was a trailer for 358/2 Days, where did you find this trailer?

 

Hm. This trailer was seen at TGS' Closed Mega-theater. Almost everyone (I think...) hasn't seen this trailer and the other two. Though, in the News & Updates section there is a three-second video of the game's game play.

The only way to see the trailer was going to TGS and watched the trailers in the theater.
