So according to Famitsu, Pokémon OR/AS got 210k pre-orders during the first 2 days. Unless I'm mistaken, they say that pre-orders are roughly the same for both versions. Compared to X/Y, pre-orders are half as good as X/Y, if you don't take into account the double-pack. If you do, it's apparently roughly the same as X/Y (same as Media Create, then).
It is for such a niche title as Fatal Frame, 66k would have been the best opening for the series. Even 27k is not too bad, it's on par with the opening of the last two Wii games, as well as significantly greater than the terrible 3DS spin off.
