You’re probably not wrong; consoles moving to x86-64 likely was a death knell.

It’s too long to post here as a comment, but I believe that the PS3 stumbling early (price, giant enemy crab etc.) resulted in Sony JP losing control of the Computer Entertainment division to Sony US, and it was that shift that signed console farming’s fate all the way back to before the release of the PS4.

The fact that the whole X/O remapping was forced onto Japan is just one example of this relative loss of power.
