compare the simpsons here...
the last season of simpsons had 22 episodes on 4 discs...
theres 35 episodes of Ewoks (reported by tvshowsondvd.com)
so im guessing it would be around a 6 disc set like jimbo said....
unless they release two 3 disc sets at the same time just labelling them season 1 and season 2....
both could be options...
