Nah, I'm not assuming people are complaining because they want Sony to continue dominating the aaa console space, I'm watching Sony fans raise the gates for an obvious threat and it's entertaining to me.I hate that you're assuming that people are complaining because they "want Sony to dominate". There are legitimate reasons to be worried or angry about this, we don't need edglelords telling us how dumb we are for being concerned.
I also agree that there are legitimate reasons to be worried or angry about this news. I've also been watching the video game industry do its best impersonation of the last days of the arcades for a decade now so none of this is particularly shocking to me. Nor is the fact that it's going to get "worse" real soon.
Consolidation bothered me more 20 years ago when EA was buying up and gutting developers I loved. Watching Sony bleed out from wounds inflicted by weapons they built the prototypes for doesn't phase me at all.
This is coming from a pc gamer that has always thought the Xbox was even more pointless than the Playstation.
