What do you think, will Nintendo release all Zelda titles from handheld consoles on 3DS? eShop will be ready soon and they have already confirmed GB/C games and Nintendo classics (?). I really wish that would happen, because I don't have a GBC or GBA anymore ...
They could even port Wind Waker to the new 3DS, it's powerful enough.
So:
The Legend of Zelda
The Adventure of Link
A Link to the Past
Link's Awakening DX*
Ocarina of Time*
Majora's Mask
Oracle of Ages
Oracle of Seasons
The Minish Cap
Wind Waker
*confirmed
