From Japan comes some interesting bits of information, apparently Sony Music is considering to reproduce the original OST to Thundersub/Blue Noah, in CD format (and quality, hopefully).
Now they are currently only considering it, so they are now taking in "reservations", a sort of pre-order I'd imagine. Now since my Japanese is... horrible I can't really tell you much more other than the link:
At the time of writing this the reservation meter is at 70% of 100%. So if you're in Japan or know Japanese and has the capability of signing up to this reservation drive then please do.
Thanks to Yukitoshi Chijiwa from Tokyo for this information.
