I saw Pure Pool a week ago but passed on it. Kind of regret it now as it's now gone from my store.
I also find it strange that you can't find these listed on Best Buy's website.
Knack was the first game I beat on my PS4 back at launch and I absolutely loved it. Such a pleasant switch from the constant stream of shooters. If Sony made a Knack 2 I'd buy it at launch in a heartbeat.
