Seems another fake rumor. This guy just saw that the last Guilty Gear was released and since it's exclusive like many of their previous games then it means Sony may buy them.
The thing is Guilty Gear, or the other games made by the studio, don't sell a shit compared to many other Sony exclusives. The exception was their Dragon Ball game, which sold due to the popularity of the IP. The game was great, but all the shitty Dragon Ball games also sell well.
I highly doubt Guilty Gear will need to sell. They recently had a huge success with Dragon Ball, their recent Guilty Gear game is awesome so I assume it will perform ok and will be the best selling Guilty Gear game because of DB fans migrating to this game. And for the future they have projects like the Dungeon Fighter (huge IP, one of the top grossing PC game worldwide during several years, many months top 1) game.
But if they buy them it would be a great purchase, these are some of the most talented fighting game devs in the world and would fit Sony's tradition of purchasing studios with a long story of Sony exclusives, and now that Sony bought EVO they'll want to secure some exclusive fighting games and IPs.
Sony All-stars 2d Anime fighting game...
Well, made by ARC would be so fucking amazing. These guys are super talented and make awesome adaptations to 2D fighting games of many IPs.
I do not think they buy developers to remove them from the competition. I think Sony is more likely to buy developers they worked a long time with and that have a good team / values / work ethic fit with the existing WWS stable.
I do not think you will see many studio purchases of multiplatform studios to ensure the competition gets less games or for the heck of it/IP’s.
Well, ARC released a ton of PS exclusive games since PS1 and other than Dragon Ball FighterZ their games don't sell a lot. To buy them wouldn't change things too much.
