I'm sure you've already mentioned it, but there was a superb re-release of Phoenix 2772 with Japanese subtitles, complete, unedited, etc.
While you were away they finally put out an original language + sub version of Nausicaa (which really would be a revelation if you've been buried underground for 10+ years.) That, and everything by Miyazaki is availble now (you probably know.)
Recently saw the DVD set of the Giant Robo OAV. Nothing great but it is something you might have had to sutffer through as dub back in the 90's but can now be watched original language + subs.
I think it is pretty old now, but there's a pretty stellar dvd of Night on the Galactic Railroad, and someone snuck out a dvd of Arcadia of My Youth (though you won't find either in stores anymore.) The new Phoenix mini-series is out on DVD (I have mixed thoughts about these) and apparently madman has reissued the Tezuka shorts with english subs (versus the Japanese version w/out subs that many of us dropped our money on.)
I probably don't follow as much anime & manga as I should, so that's about as helpful as I'm going to be able to be.
And two questions from me:
1) Where the hell is the original animated movie/series Galaxy Express 999? It has apparently never been on DVD even though it is considered legendary.
2) All of the Galaxy Railways series is currently available for cheap on DVD (6 discs for $30 or something.) Any thoughts?
Edit: scoped Amazon. Arcadia of my youth is now rare/out of print fetching over $80. Should have picked a couple up on DVD when it came out. Also noted that apparently Galaxy Express 999 is available from Korea region 3. Wonder what the quality of the sub is on that?
