Marriner Schubert Box with symphonic fragments D708A, D936A (Symphony 10), D729 (Symphony 7), and D615:
--- 1986: Philips original release in two 3 CD plastic boxes + separate booklet in a cardboard slipcase.
--- 2003: Reissued by Philips in 2003 - gray cover - the copies I have seen come packaged in a 6 CD plastic case (boo). Was it later repackaged in a cardboard box?
--- 2011: Reissued by Newton Classics in a 6 CD cardboard box
--- 2013: Reissued by Philips on their German Eloquence label (not the same as the Australian Eloquence label we all know and love), now in a 5 CD cardboard box without a booklet, but it claims to be newly remastered.

The 5CD 2013 box has the same music as the earlier 6CD boxes, but in new remasterings.
The German Eloquence label also remastered Bohm's Bayreuth Ring to excellent reviews in England, but I haven't seen any reviews of the German Eloquence Schubert. Both German Eloquence boxes seem to be out-of-print.
