The sales got a boost because they were selling for as little as $100 near me last Christmas. I'm sure they've slowed way down since the deals went away.
Yeah, I jumped in this Christmas with a $250 bundle with 2 games, move controllers, and eye.
With that said, the last two holiday seasons have had great deals. And, with a likely slowdown in console sales ahead of the PS5, I can see Sony aggressively discounting PSVR again this year, so they have something to pick up the slack
If they were to leak info that it will be PS5 compatible, that would also help.
