I am pretty sure we will be shocked by Nintendo there is a reason why Nintendo dropped Wii support like 4 years ago.
Sure they had a ton of 3DS games but just look at Luigis Mansion for example this is completely developed by an external company with Nintendo's only contribution to it being their supervision and general "plan" for the game.
Other games like
Mario 3D land are rather simple (still great tho!).
Mario Kart 7 also had Monolith Soft supporting it etc.
Starfox 64 3D and Ocarina of Time 3D are ports made by Q-Games and Greezo with little support by Nintendo.
This shows that Nintendo had smaller teams working on 3DS games than they usually have for their big titles or completely handed development over to external companies.
Nintendo has a ton of collaborations right now so their main studios can concentrate on WiiU.
