Will citra be able to run 2ds games in the future

dolphin can emulate gcn and wii and vbam can emulate gb/gbc/gba games, so is backwards compatability is in development right now for citra devs?

Citra supports 2DS, 3DS, and will in the future, support new 3DS titles. There are no plans for backward compatibility, as those emulators do it better and do it well.
