Korean Air Skypass - LAX-ICN Prestige Seats?

Planning a trip for the first week of November. Might do LAX-ICN on KE006 or KE012. What is the state of the Prestige Seats on either of those two? Old, Plus, Sleeper?

Take KE012. All except 005/006 has plus. 005/006 is currently planned to have old version, but will be upgraded to plus on Dec or Jan 2010. There's no sleeper on LAX route until early next year when KE001/002 (via NRT) is upgraded.
