Nobody should touch any coin, but only inform about the weaknesses. The coins that aren't provably burned, exist, and can, therefore, enter the market at anytime.
Don't forget Satoshi can't sell his coin without attract attention or potentially de-anonymize himself, so it's very unlikely it'll happen.
Moving the coins, alone, doesn't de-anonymize, though.
