Does this mean that Tekken 7 will be Playstation exclusive?
And why are he saying that it will be Playstation exclusive and not Playstation 4 exclusive, could this mean that this game could come also to PS3 or PS Vita? 

He doesnt say its exclusive, the lead platform is PlayStation though. its coming to xbox one.

Maybe, Sony is in a position of power now it wouldn't take much to get exclusivity form one of their home devs.

Business wise it makes sense, sony helps with dev and or promotion. Much of the risk is negated for BN while they get boost for being "exclusive" and get to create a better Tekken due to no forced parity.

Guess this is what you get when going to sites like that. Site taking sgit outta context and you doing the same.

Not a single mention was made about the XB1, so there is no indication that it won't be coming to the XB1. Just confirms it won't be on the PC.

It does say here that it won't come to PC since there isn't a fanbase there. While it's likely the PS4 is the lead platform, I wouldn't rule out the Xbox One version.

Also, that last tweet was hilarious.

Tekken seems to sell quite well in US, even moreso than in Japan, so an X1 release seems quite possible if the it stays as strong as it is right now.

I don't think that the fact that it's developed on PS4 as a lead platform has any effect on a possible X1 release. It's not like it would be hard to port since it will probably run as well even unoptimized.

It seems more like he was simply saying that the PS4 is the lead development platform. I wouldn't believe this until someone explicitly says "it's only coming to the PS4".

I dont see him saying it will be ps exclusive :/

To be honest, i'm not sure it was announced to any console (it was announced to be using UE4 and arcade). This is basically a confirmation of PS4, but we dont know anything else.

With SFV beeing a PS4 exclusive one does have to wonder. The PS4 is going to be the fighter platform. X1 is a complete failure in Japan aswell, so its not surprising that they arent clear if its coming to it or not.

no it doesn't make sense business wise releasing to a smaller user base ever. Ever. And it's silly how people think Sony or even ms will throw money at ever publisher to "help with dev" whenever the word exclusive comes up. With games like these or with publishers in general, they would always consider where they stand to gain the most and if everything else is worth the investment.

Outside NA, all these devs know that the XB1 is dead, with exception to Europe, so these games will most likely release in NA and Europe for both the PS4 and XB1. but outside that, there is no point cause the game may very well be exclusive to the PS4. Take mgs5 or FF15, there is zero sense for them releasing on the XB1 in Japan cause by the time those games are out the XB1 wouldn't have broken 50k sales in that region. PS4 exclusive by default.
