It's worth noting that very few evolution methods have been disallowed in each remake just because they didn't offer the facilities for it. FRLG didn't allow day/night only, though friendship was locked until aftergame HGSS didn't allow location-based evolutions but actually allowed everything else, albeit you could only get dusk/dawn/shiny/whatever stones in the aftergame. The only evolution methods introduced since then - unless I'm missing something from Gen 5 - are Inkay, Sylveon and Pangoro. They've already shown Amie exists, you can easily have a dark type in your team and something makes me doubt the 3DS' gyroscope will be locked.
