There is already a very different dynamic to the ground battles in ESB and ROTJ.

In ROTJ the AT-STs are used as the primary ground assault vehicle and the speeder bikes are used as scouts in a crowded obstacle filled environment against ground troops and teddy bears.

In ESB the AT-STs are the scouts to the AT-ATs on a open battlefield against mostly air assault.

If the Endor ground followed the same arrangement it would be more of the same but with added obstacles (not that I wouldn't love to see a single AT-AT pushing trees aside like something out of a Ray Harryhausen movie but that's for another thread).

Having each film introduce a new craft has never been a fetish of mine but the TIE interceptor is there for those who want it.

Naturally different situations would call for different craft to be used.

X-Wings Vs TIEs over the snow might have been cheaper and easier to do for ESB but would not have been anywhere near as cool and using space fighters over a planetary terrain seems a little odd.

The additional glimpse of an exotic other walker was one of the gasp moments of my first viewing of ESB (I turned 40 recently but I remember the first viewing of this film really well).

I thought it was a great touch that had bothered to throw in another type of walker in there, it looked so distinctive but also looked like it came from the same school of thought that gave birth to the larger version.

If that feature can be made to work better I'd prefer it to be there somewhere than to lose it all together.

But I say again it's not my call to make.
