There have been rumours circling for some time that an upgrade to Wii Fit is on its way, and now there appears to be proof in the form of the above logo, filed with the Japanese trademark organisation.

There a no publicly available details of the new product, but that hasn't stopped people theorising. Reuters is reporting that it will allow you to link up with other Wii Fit Plus users over broadband.

We know that Nintendo has been recruiting fitness experts to help them provide more advice and guidance to Wii Fit users, hopefully this will form a core of the new game, with structured workouts such as those found in My Fitness Coach and EA Sports Active.

There have also been claims that it will feature improved accuracy from the balance board. Hopefully this will be am improvement to the software rather than a new piece of hardware; I can't imagine many Wii Fit users wanting to fork out to replace their existing board.

Gamespot are suggesting quite reasonably, that we might see a preview of the new Wii Fit Plus at the Nintendo E3 Press Event at 9am PDT, 2nd June.

Fingers crossed. I have high hopes for Wii Fit Plus. If Nintendo can keep the production values high, while adding some of the best features of the other exercise games out there, this could be a really worthwhile upgrade.

My personal wish list is:

• Structured workouts targeting specific goals.
• Less time wasted between exercises.
• More variation within each of the games (there is only so many times you can hear the same tune in the Step session before it gets very boring).
• More cardio based exercises.

If you could add anything to Wii Fit Plus, what would it be?
