Really hard to say. They could push it for a long time and have a lot of hard-hitting games and maybe it could but like I said it's hard to decide right now. As of how it's going, no. GBA will win. But who knows what they have for 2015. Maybe even 2016 they'll have a full year for 3DS. My guess is they announce new handheld/mobile device next E3 and release it either late 2016 or early 2017.
