^ I don't think speederbikes would make for a logical addition to the Battle of Hoth. Their use makes sense in ROTJ because, given the density of the forest, they are the only real means of transportation (aside from the AT-STs). On Hoth, however, any Imperial trooper riding a bike would be an easy target for the rebels. The idea for the Empire here isn't speed, it's defensibility while making a frontal assault (which is where the AT-ATs, with their impenetrable armour, comes in).

WHA?!?!?!

So it makes more sense to have speeder bikes in a dense forest of huge trees that you can run into and kill yourself in less than 10 seconds from starting your bike, as opposed to a snow planet that has nice flat fields to fly around it without running into anything (other than the falling AT-ATs and snowspeeders). Speeder bikes are also fast and extremely small, making them HARDER targets than the large and slow AT-ATs, which would be a priority to destroy more than speeder bikes.

Granted, I don't think I would want to see speeder bikes just because it could clutter things up (though if someone could do a test to show what it could look like...). I still like the earlier idea of having snow troopers bailing out of the AT-AT that falls down from Wedge's cable though, as well as maybe showing them repelling out the side of an AT-AT in a later shot (maybe) or debarking in some fashion.

EDIT- looks like I got beat to the punch again.
