[KRAFTWERK] Clarification on Der Katalog

[Toby Frith]

Can anyone tell me if these LPs have been "rerecorded" or just "remastered"...... Is there any official documentation available yet?

Given that they've given most of the LPs new covers, is it likely that they've been given a good going over? 

I know this info might have been posted recently, but I've just had a holiday and had to delete my inbox sharpish....
