It's funny cause I actually just recently bought a Wii 2 months ago, #1 to play Skyward Sword and #2 to play old GC games that I kept after selling my GC (such as WW, TP, OoT MQ, SSBM), and so I bought a refurbrished one that is practically new for $80 with tax, which is almost how much I sold my GC for.
But yes, there hasn't been a remake because of this backward compatibility, but I can definitely see them rereleasing it on Wii-U as a virtual console title, or even the Wii-U's successor as a remake. If they did end up remaking the game and improving some areas of it as I would hope, I wouldn't think they'd rush to do so in the next 10 years.
