the shell of the mouse will actually be PBT.
sensor is the 'famous' 3310, which has pretty much become the standard in gaming mice.
it uses omron switches.
you will be able to change the RGB lighting without drivers.
you will be able to change the polling rate without drivers (125, 250, 500, 1000).
you will be able to change the dpi without drivers (400, 800, 1200, 1600, 2400, 3200, 5000).
you will be able to adjust the LOD without drivers as well.
sounds pretty slick to me.. :-)
the only thing i am a little skeptical about is the sensor placement. (it looks like it's placed just a tad too low.)
this album has a few photos of the mouse (including one of the bottom):

(the photos in the album were taken at computex, they also show some other new ducky hardware.)
there's also a video/trailer of the mouse:
