i think only the players choice titles, and best sellers, will remain on the shelves at most of the major retailers. GS is bound to have all the used games to profit off of, but for the ones that arent used im sure they will atleast keep the players choice/best seller around, even if they have to clump em together in some bargain bin (with the used ones)
i've actually been wondering about this for awhile now so i've been stocking up on a bunch of GC games, new or used, as long as their cheap. i figure just in case they dont carry as many, i'll stock up now, even if i dont play them any time soon, and keep them around for those times where there might not be any wii games that ineterest me.
