Wii Sports Resort seems to be doing great in Japan.  The game has sold over 350,000 copies during its first four days in retail.

Hopefully, this is an indication of what may become of Wii Motion Plus.  Some reports say that the game’s release may have even had an effect on hardware sales, as those are up to 21,790 over last week’s 19,386.

Now, if only Nintendo would begin to create Wii Remotes with built-in Motion Plus tech. We’d be set.
