That assumes that NRS is even available for purchase or that their asking price, if they are, wasn't deemed too high. As far as I know, none of the Warner Bros studios are currently up for grabs and will be transitioned to Discovery as planned. The only exception being Playdemic, a mobile developer, that EA just bought for $1.4 billion. I can assure you that in the event NRS is made available for acquisition the competition for it will be fierce and EA has already been making it very clear they want to gobble up the Warner Bros studios since last year. None of the other companies who are worth a damn that make fighting games (Capcom, Bandai Namco, NRS) are likely available. So if Sony was looking for a studio to make exclusive fighting games for them, AWS was the most likely of the four to be up for acquisition and they fit very well with Sony's apparent plans. Not to mention being in a much more digestible price range.
