I haven't chimed in on the release, so I'll just say that I prefer amaray to digipaks but to elaborate further, I prefer amaray to massive digipaks like the ones that were used in previous Ultimate Editions that Anime Limited have released. Not only are they flimsy and unwieldy, but I generally find that the mechanism used to keep the discs in place to be finicky at best. I received the Patema digipak cracked in pieces and the trays that came with Lagann fell off and these two issues have pushed me to never purchase Anime Limited products again.
I will say that in regards to the use of Amaray, using different colors like black, white, Red or even the clear ones Anime Limited have used on previous releases (Garden of Words and Dandy) is preferable and helps make them stand out a bit more and feel a little more special as apposed to the ugly Blue ones, but since the Japanese set also used Blue amarays I'll let that one slide. The fact that this box is large even-though it houses amarays is also annoying. I've never ever cared for art-books that come with games and Blu-rays/DVD's, even if it's full-sized and extensive because If I care enough about the show I'd pick up all the art-books and full soundtracks separately, which is why I hate it when you get a soundtrack with a game that has 10 tracks or thereabouts. If the OST is good, I'll splash out the money for the 5 disc soundtrack thanks very much. Of course the reason why it's done is to help justify the cost to people at home, but if you look at most Japanese Limited Editions that sell for double the price of this FMP set, they rarely if ever come with any extra outside of the show itself and a box and maybe a little booklet. The reason to me is simple, if a show is good, that alone will justify the price for core fans, the people who are most likely willing to buy the OST and artbooks/figures separately and the remaining people will pick up the standard set as always. And if you do want to make an extensive set with everything and the kitchen sink, make sure its something extra special, like say the Gurren Lagann Japanese Blu-ray set. It comes with a hefty price point, but again it sold out for a reason, people are wiling to buy something if its something they love and care about. I know people who don't buy into expensive sets importing the Eva BD set even though it's not English friendly. Good shows tend to attract people. I understand that I'm in the minority here and that's fine, people obviously like their artbooks and Anime Limited have put effort into it.
In the end, this is a positive move in the right direction. I like digipaks, but the Anime Limited releases have failed to deliver with these. I do like the inside art on the Perfect Blue digipaks however and the finish on the SAO II digipak looks nice if you want some positives.
Also to comment on the above, I prefer 'bland' discs art as apposed to discs have have tacky art all over, but that's me. That's just a general comment, I can't comment on the FMP disc art.
