After I beat this 3DS game, I'll be done with handheld gaming until next generation.

So your gonna miss some of the gems/games that have already been announced such as

Dragon Quest VII
Dragon Quest VIII
Mario and Luigi Paper Jam
Fire Emblem Fates
Final Fantasy Explorers
Bravely Second
Metroid Prime FF

The 3DS still has plenty of life so you shouldn't discard it so easily until it takes its last breath!
