An existing publisher buying another publisher is not really an efficient use of capital. MS is doing it because, frankly, they have the money to burn.
It's absolutely possible for Sony to grab their own publisher, and if they were asking me for advice there are a few that make a fair bit of sense. But they can't do it just because MS has done it to make a point or something like that.
My bad, I didn't intend to imply that Sony were doing it
purely just as a response to MS doing it or just to make a point.
More that it absolutely affects their future business plans. Just look at all the Bethesda timed-exclusives; Starfield was going to be a part of that - Not anymore.
MS clearly disrupted that strategy and threw a wrench on their plans. All of those future games are 1st party MS games now.
Future Call of Duty games? Yeah, another gigantic PlayStation associated franchise, gone (eventhough I expect the next two CoD's to make an appearance on Sony's console).
Future games? They'll all be exclusive.
That's a
huge vaccum which I can't see Sony ignoring anymore, eventhough we might not see the affects of this acquisition until sometime next year (as was the case with Bethesda).
So again, they obviously won't just do it on a whim - But I fully expect them to now.
