The difference is that MSFT actually gave us good games to play last fall, so there is somewhat of a hangover. Plus if you count until dawn, how can you ignore Ori and the Blind Forest or State of Decay YOSE, heck or the new seasons of KI. Also NeverWinter has a ton of players, why doesn't that count.
Judging by overall reaction the last good game ps4 had was either tlou remastered in July or infamous in march. That is the difference. Also BB launched in March and the next big game won't be until Uncharted. I would rather have holiday releases than a gap that big, 13 months probably. (Using assumptons just like you did)
