Not too surprising, actually. Sony do have a habit of buying whole studios, but there was no point of them doing it in this case. If noone bought Vigil, they could simply hire some of the key staff members afterwards. Makes sense, really. Could stick some of them on the GoW development team and them move some of the long-time SSM staff over to the new team working on the FPS.
Don't see why they'd buy the Darksiders IP though, just doesn't make much sense. It's not like buying Volition because Saints Row is a 5+ million franchise and Darksiders, apparently, struggles pushing 2 million. Nor is it like buying a studio with a game nearly finished, because DS2 literally just shipped and it would take a couple of years for DS3 to materialise. I get that it seems to be beloved on VGChartz, but I'd be very surprised if Sony picked it up.
