Called today for the replacements. They don't have them ready yet but they took my info and will contact me when they do, and then they'll send the discs out with mailers. Some vague but encouraging news from a post at UltimateDisney forums...
I think they may release the remaining Donalds in bulk (two volumes) next years and that'll be that. Next year the Legacy collections will feature the Oswald shorts and Destino, so it too will feature annimated content.
