All merczs have survived except SBS565M to SBS581R, waiting for
de-registration at Now 2009.
Relax lah.SBS565M-SBS581R would be refurbished soon.They are still
not refurbished yet because some of the Mercs from the 55x series
are still getting or yet to be refurbished.So most likely,the Mercs
in the SBS565M-581R batch will get refurbished when the Mercs
in the 55x series finish getting refurbished.
