It would be nice, but I don't think it's going to happen.
They've already stated that all the GameBoy Ambassador games would be for Ambassadors only and would not be released to the public. I know that many people would be somewhat upset if they changed their mind and sold MC. While it's admittedly selfish for ambassadors to have it for themselves, it's not fair to Nintendo to allow others to have what was supposed to be their special privilege for buying the 3DS early.
As an ambassador myself, I know that I'd feel somewhat insulted if they released it for the public. It's not so much that you lovely people would be able to play Minish Cap as well, but it's more that Nintendo went back on their word.
