Will the Beatles collection get converted to DVD-A or SACD?

Answer 1

I'm not sure about the high-resolution formats but as we speak Apple Records is remastering all of them for reisue. Hopefully these formats. Do you want it for the surround or just greater sound? I'm for the latter.

Answer 2

Hard to tell; I believe the British record company Polyphone owns the original mono masters. They have remasted in mono only.
Capital records (in the US) have there Stereo masters that they got from the British masters. Captial has released remastered sets with both the mono and stereo versions, and that may be all we see. The quality may not justify the cost of production and the investment.
