Should I sell my Wii U games now or later?

I can no longer play my Wii U because I acidentally broke it awhile back, but I still have my collection of physical games that all still work. Do you guys think they will go up in price or should I sell them as soon as possible? I very much want to sell them so please don't tell me to keep them forever, I just don't know when I should sell them.

Game collection: Wind Waker HD, Mario Kart 8, Catain Toad, Super Mario 3D World, Bayonetta 2, ZombiU, Splatoon, Smash 4, Kirby and the Rainbow curse, Donkey Kong Tropical Freeze, New Super mario bros U, The Wonderful 101, and Pikmin 3.
