It seems that James Dyson has got something up his sleeve, and with a global launch planned for tomorrow, a teaser has hit the Internet.

Hitting play on the clip above is your best way to get an idea of the mysterious video that shows a range of seemingly ordinary consumer types react in an astounded fashion to something they are shown.

There are "wows", "whoas", "what is that?" and "oh my goshes" galore as the device makes a slight humming noise in the background. One good guess would be the blade-less fan design the company recently patented.

A bleeped out question sounds very much like "where are the buttons?" but if you spot anything else that could be a clue, or have a guess as to what it could be, let us know in comments and when we bring you the official news tomorrow we'll see just who was closest.
