It would be smarter to actually wait and see what we get, but since we have nothing else to do until then it's time for shits and giggles.
I give you a brief sampling of anime Blu-ray releases:
Olde, traditional painted cel, shot on film stuff:
Patlabor Movie I (1989), delicious 35mm film properly mastered(Bandai Visual):
Memories (1995), 35mm (Bandai Visual):
Gunbuster (1988) is a fun case to bring up because it's all well mastered, but the interesting part comes from the source material. Episodes 1-4 were shot on el cheapo 16mm film and eps 5-6 (the two most full of epicness) were shot on 35mm film(Bandai Visual):
16mm:
35mm:
Zeta Gundam (1985) another fun case (Bandai Visual):
Creditless OP, 35mm master:
The episodes however have only 16mm master, so you get to see the same cel shot in two different ways:
Now here's what happens when people start to fuck with the old stuff
DBZ Movie 7 (1992), what was probably delicious 35mm film at one point horribly overfiltered and oversaturated (Funimation):
Last year Oshii decided to "update" the original GITS (1995) to match Innocence (2004). He did this by replacing stuff here and there with 3DCG and bluring the rest while adding an orange tint(both from Bandai Visual):
Original:
GITS 2.0:
And finally here's what shiny pure digital animation of today looks like:
Gundam 00 (2007) (Bandai Visual):
Michiko to Hachin (2008)(Media Factory):
Macross Frontier (2008) (Bandai Visual):
Samurai 7 (2004):
Diebuster (2004-2006) (Bandai Visual):
Girl who Leapt Through Time (2006):
Gin-iro no Kami no Agito (2006):
Innocence (2004):
Moral of the story: there's still a 90% chance Rebuild BD will look totally fucking awesome, it just wont look how digital animu is suppose to look.
And for final shits and giggles, Disney's Sleeping Beauty (1959) shot on 70mm film:
(And before anyone ask why these are all huge PNGs, it's because JPEG compression would add artifacts that weren't actually in the video source. That and to annoy anyone who's still on dial-up.)
