It's a good thing from a sales perspective. Let's be honest here, third party devs rule this industry, and whichever company gets the marketing rights to the biggest games, gets the highest sales, particularly in the US during the holidays. I'm a big PS fan, and I still don't care for them, personally, but at least Sony isn't using it as an excuse to only release 2 or 3 big AAA exclusives per year. There's still 10 left to go for the rest of 2015, alone.
