Nintendo Readies Wii Remote Plus?

Quote

We played FlingSmash in February of this year and quite enjoyed it, as our First Impressions show, but its projected release date of Summer 2010 has been and gone without the game hitting shelves. Now retailer Gamestop has released boxart of the game showing the game is set to be bundled with a Remote, seemingly containing MotionPlus built-in.

Titled "Wii Remote Plus", the controller itself looks only slightly different, with a slight curve below the four lights the only alteration visible at this resolution. As FlingSmash requires MotionPlus this is obviously a new controller containing the add-on, but could the game's delay have been caused by the newly developed Remote?
