BDs coming soon.
I want to penetrate this loli.
The Hidamari S1/S2 BDs were recomposed from the original digital assets shaft still had.
Some of those assets were of a higher quality than the original 480p TV broadcast, resulting in sharper quality for a fair bit of shots.
(Some of 'em were still QTEC'd though)
PPD might get the same treatment for its BD release.
Why not just rewatch? You're just as lucky for living long enough to see them get BDs, anon.
Wildest dreams: Remaster.
What we can realistically hope for: Upscale from better-than-DVD source (square pixels, progressive video).
Probably: QTEC and a half.
