Well, I disagree.  Nintendo establishes Player's Choice on games that sell well, and labels chunks of games at a time.  I believe Smash Bros. Melee never really left the top ten GC sales, yet it was still made into a players choice.  However, I think they like to brand these games in late winter or early spring.  I think we'll see the first DS and Wii games with a "Player's Choice" banner by April, if not earlier.  My guesses:  Canvas Curse, New Super Mario Bros., Animal Crossing, Wario Ware: Touched, Wario Ware: Smooth Moves, Twilight Princess, and maybe a few others.
