Why would any of those games be at Sony's conference? With the exception of Eyedentify, which has been all but confirmed being cancelled for years, none of those games are being published by Sony and none of them are strong IPs such as Final Fantasy, Assassin's Creed, or Metal Gear.
In any case, Ni-Oh was thought to be cancelled for years before it recently reappeared in Famitsu so it will most likely be released in Japan some time this year.
Data-Fly was only just announced a few months ago.
I don't think anybody really knows what happened to Cellius (Brave Arms developer) They were a big thing back when the PS3 first lauched but nothing seems to have every come of them.
I've never even heard of Big Time Revenge or Little House in the Plateau.
