I wonder how that has influenced HC's policy towards making such limited deluxes. Maybe you got some signals about that during your correspondence with HC regarding a LoTR (super) deluxe Trotter? And does HC regard the 1992 Alan Lee deluxe set as their LoTR SD?

They could have issued a super deluxe for the new LOTR and limited it to say 500 copies, but choose not to. I think it is easier for them to sell 'unlimited' deluxe editions.
