While the States will see it on 8 June, European gamers will have to be patient until 12 June to get to grips with the Wiimote add-on.
Those waiting for the Wii Sports Resort/MotionPlus bundle will have to hold out a whole six weeks longer, until 24 July.
For an idea of what all the fuss is about, the peripheral will clip onto the bottom of your Wiimote and add more precision to your gaming, detecting 3D rotational movements as well as side to side and front to back.
EA's Grand Slam Tennis, also due in June, will be one of the first games to take advantage of Nintendo's new tech, with other titles confirmed as compatible including Sega's Virtua Tennis 2009, and Tiger Woods PGA Tour 10.
No UK pricing has been confirmed, but with a US cost being touted at $19.99 for the peripheral alone, we'd expect it shouldn't set you back more than £15 or so. Let us know if you'll be coughing up the cash for the MotionPlus below.
