This is why the Sony wand is better for full out motion controls than wiimote alone (and the same in accuracy to Wiimote+Wii motion plus, but with the advantage of not needing to callibrate it) but not as accurate as a pointer because it has to use the motion sensing more to figure out it's angle.

This is speculation until we get our hands on it. Hardware-wise, as you said, it uses gyroscopes+accelerometers just like WM+, so it's potentially extremely accurate with angles.

Software-wise, it all depends on how they want to convert translations/rotations into cursor movements. The tech demo with the guy writing up his name seemed to show excellent controls, he even remarks that it's easier to control a cursor using translations than rotations (something on the lines of: it's hard to write your name with an 8' pencil).

It's not speculation, it's just how it works.

The Wii remote is a camera using 2 reference points (IR light on either side of the sensor bar) it can recognise tilt and left-right angles instantly (well at the camera refresh rate anyway) and only needs to do checks with the accellerometers if you point off-screen (if you notice, on occasion if you point off screen, turn the remote upside down (buttons in palm) and point back at the screen, if you have done this quick enough the little on-screen hand pointer is still the correct way up because it hasn't yet registered the remote is upside down)

With the sony wand thing, it's a camera tracking a single ball... it can trackthe ball position instantly, but you could have the ball in the same position and twist/turn the rest of the wand around it in any direction you like... without the motion sensing in the wand the camera can't track which angle the wand is pointing.
