Actually many systems have 11.0 now. You said it yourself, they make the systems in advance.
and we've had 11.0 for quite a while now. At least 3 months
Like I said he could get one on 11.0 but he may not also. From his flag he lives in a country where they don't manufacture 3ds' they're probably still getting old firmware there. They don't make them 6-9 months in advance with firmware that isn't out yet.
