Nintendo has told Eurogamer that July release dates for MotionPlus and Wii Sports Resort are "purely rumour and speculation".
Timings are "still TBC", added the spokesperson - dismissing leaked retailer information from Holland (displayed by GoNintendo).
Specifically, that information claims Wii Sports Resort and the MotionPlus controller will arrive on 10th July, both as a bundle and sold separately. The same schedule also says Wii Fit Plus will be released on 19th November.
Nintendo US boss Reggie Fils-Aime also recently dodged Wii MotionPlus date queries by squashing June rumblings and sticking to the "spring 2009" estimate promised at E3 last year.
The MotionPlus accessory clips into the bottom of the Wiimote and allows rotation around the X, Y and Z axes, resulting in six degrees of freedom.
Wii Sports Resort will showcase the new technology, and impressed us back at E3. Furthermore, claims Reggie Fils-Aime, "the level of motion capability is far in excess of what we showed at E3".
