Nintendo are in a remaking mood recently, We've had OoT and they seem to want to remake ALttP whereas the fans want MM3d, granted OoT and MM are already 3D but ALttP, and while its vague as to what ALttP would be/would have been should it ever come to exist there is a possibility of it being 3D which means a lot of work for nintendo or whoever ever they lend the game out to, you cant remake a 2d world into a 3d world like OoT especially when ALttP remains a paragon of Zelda's 2d installments, for this reason alone of the work involved it'd be expensive and time consuming for whoever were to change the whole engine of the game, so i don't think we'll get any 2D games becoming 3D, not when nintendo like to make new things and try new stuff in terms of gameplay.
That being said, were the games to be made into 3d they'd sell like wildfire. old fans are very attached to the 2d games because they grew up with them, i myself really love Link's Awakening and have been clamouring for a mad off its nut installment just like it in the 3D world, we got MM but that wasn't the same it did show us though that nintnedo aren't against going crazy with zelda every now and again...
So i'd really love LA in 3D and i'm sure others would really like Minish Cap or even Adventure of Link in 3D, though i can't see it ever happening.
