Looks like you are out for a larger discussion on this point. First, I have no information on aes being broken. Second, I´m not making a guess on how long a brute force attack on one of the encrypted blocks might take.
The idea behind the advice to shred/overwrite a complete disk is simply not to leave files from previous installations/unencrypted behind. Formatted disks can still leak files, so simply overwrite the disk completely and you are done.
Kind regards,
Peter
