Based on the life of the DS and 3DS's current furtunes, I'd say the 3DS's successor will come out no earlier than Holiday 2016 and no latter than Holiday 2017. Probably alongside the NX console, but things can vary. And of course, Nintendo supported their older handhelds after their successor were released. The DS was released in 2004, but the GBA got a fair number of games in 2005, like Pokemon Mystery Dungeon, Mario Party Advance, Mario Tennis: Power Tour, DK King of Swing, and Drill Dozer. Later on, after the 3DS launch, the DS received Kirby Mass Attack, Pokemon Conquest, and Pokemon B/W 2.
So my guess is about two years or a bit more of new notable 3DS games.
