I may be mistaken, but I think Kagari from GAF (who usually knows what´s up at SquareEnix) implied Sony was funding the development of the game.If that´s true then do not expect it on a Nintendo system nor on the X1.

Isn't it sad that people already assume that Nintendo will need help selling consoles?

Nah, it's only going to be PS4 and PC

Doubt it. It will likely be multiplat so that they can increase the revenue from the game as much as possible. SE needs this, as well as their other games, to sell as much as possible.

There will be never a Xbone Version of the Game. Thanks God, the Xbone dont deserve a game like this. Sony btw is allowing PC Versions, because they will get Money of the sold PC Versions too, for every Game like Shenmue 3 FF7 Remake, and SF5. And they allow it, because PC is no threat for consoles

In the conference they said something along the lines of 'coming to PS4 first' or something like that.

They're probably still negotiating. I'm sure Sony's main concern is keeping this off Xbox. Maybe a PC release down the line though. No idea about NX since we still don't know what it is.

Its because it will come a half year later or so, for the PC, to make even more profit with the game both of them SE & Sony

Maybe, but for most of the games that they mentioned that were PS4 and PC, they actually stated that. It shared very similar wording to the trailer about Star Wars Battlefront, with the exception of bobafett.I think it's too early to jump to conclusions yet. Far too early for people to get worked up and jealous one way or ther other lol.

here is my line of thinking.

FF VII is a huge part of PlayStation's historical identity. They will do everything they can to make it console exclusive. That said even FF VII had a PC release, so if it makes a console exclusivity deal more acceptable to Square letting the game be on PC they would be fine with that.
