It's only been out for two months for consoles and it's already been at Gamestop(just looked it's back up to $40.) It's out of stock at the two closest Gamestops to me, listed as low stock everywhere else and still available online. So for consoles, I'd say it'll be rare or atleast very uncommon once they completely sell out at other retailers.
I wouldn't jump on it yet though, I'd wait for it to hit $20 again or starts to become harder to find everywhere.
