These titles have reverted back to Sony in the USA, so new CD editions are being put out through their Columbia/Legacy imprint. (There's no new remastering or bonus tracks, Sony is simply getting these discs back into print.)

The only issue I had with the Pink Floyd remaster series is they didn't complete the catalog (hi res would have been nice too). They should have added an extra disc in the complete albums collection that would have collected all of the non-album tracks remastered. If Relics was remastered it would cover several of those tracks. Interesting they're going back to the original cover. I don't believe it has ever been issued on CD in the US.

There was a Division Bell 5.1 DVD-A, but it seems to have disappeared.
