Of course it'll happen. Nintendo gotta milk the series for all dat money.
I don't see it happening in the near future.
Don't bother about it, cause it's not going to happen.
Hello Nintendo, I didn't know you joined this forum.
im sorry dude, with MM wont work like OoT can work.
the new features on the Oot3D were the boss rush and the inverted master quest.
boss rush: already exist on MM, you just need to teleport to a temple, enter it and just go to the boss, you dont need to do the dungeon again and can be done by just going back in time if you already killed it
master quest: Oot already had a masterquest coded, you didnt need to make anything new -at all-, MM doesnt have a MQ so its not just a sprite revamp, they need to redo all the dungeons.
inverted map: MM has a circled map... you wont be making much difference inverting the map.
I am sorry, i want a MM3D, i just dont see it happening in the near future... if they release a new zelda for the 3ds, only diehard fans of MM will be interested in getting it (not every zelda fan likes that game) and it will take time until they create a MQ for MM.
so this game is not in the near future, and it wont sell if it is released after a new zelda - meaning if this game is released it will delay a new zelda.
