not exactly true. for perspective, Alien Head has 2 versions: the japanese and the world release (R2UK/R4). the japanese has more extras like kubricks and all. please post if the item for bid is the japanese release. at $100, no true collector would let go of this HTF and most sough-after set.
the decline in consumer purchase is directly related to economic reason and not because of the advent of HDDVD/Bluray. dvd category still holds majority of the share in terms of sales. in fact, markets all over the world still enjoy superlative dvds support and patronage. in the Philippines, the scenario is quite different.
i would suggest that you still buy LE's at this point and continue to grow your collection.
