What a scam. Release the first three films, then release part 3, then release eps 1 2 and 3 boxset, then 4 5 and 6 boxset, and then a super 6-disc boxset.
Then, 6 months later, release a limited edition 6 disc boxset, then ignore the limited bit and re-release it. Then, another year or so later, release a 10 disc super duper boxset. Then a bit later, put it all in a tacky plastic r2d2 and release the lot again.
