Personally I think the sales are inflated due to the lack of competition for RPGs on the Wii U and secondly due to the lack of games in general.
Nintendo fans didn't have much else new to choose from in November and December so it's inevitable that X gets a boost. 200k+ in the US is definitely good for the game but you're not going to see 3Rd party RPG developers rushing back to support them.
