I recall the wardrobe, but for me OHMSS was a bit before my time (I would have been around 8 at the time it was originally released). So while it is obviously different to me, I wouldn't really be able to identify what would be typical or over the top for the time period. So luckily, no...
I'm sure they will be, but I seem to recall discussions where later releases of a same master can be improved by using a more advanced encoding. Not an expert in the area but that is what I perceived from the discussion. So if true, that is where i could see them marketing a better release.
I'm with you in wanting those first two and possibly Diamonds if available separately or in combination with the other two. Otherwise, I have the one's I wanted most on BR and the rest in the ultimate DVD collection, which is good enough for me.
But given past history, I see these as coming...
