It is limited edition, comes in a nice box with an artbook of production sketches and a couple soundtracks (that every collector already has multiple copies of by now). I know I'll be able to find copies on yahoo japan auctions for years to come, but whether it'll cost more or less depends on just how many they make. I think I'll keep an eye on used copies for the next few months, as it'll probably be cheapest from anybody wanting/needing to offload their copy right away, then the used price will rise sharply once the stores are all sold out.
Agh, if this was just another DVD release I could easily ignore it for now, but a new transfer for Blu-Ray and the first pressing is limited edition? If it weren't for the fact that I literally do not have the money right now, I probably would've already ordered it.
