This will probably take a long, really long tome, if it ever even happens, Citra needs first to get more optimized, and they released their ARM fix just now, this relese is probably done just to try it out, just for the sake of it.
If I were you, I would buy any 3DS revision if I don't have one already instead of waiting years, and we are uncertain that it will ever even work with stable performance, Pokémon games are some of the most resource heavy for the console.
I just looked up used 2DS's, they are like 55-60 dollars or so at Amazon right now.
