Well, it might be a little early to guess…but:
Theoretically LDW-411S -> LDW-811S could be possible.
(That’s just what we are used to from LiteOn.)
Maybe LDW-411S -> LDW-811S -> LDW-812S could even become reality.
But first LiteOn should release new LDW-411S firmware with better media compatibility.
I hope I will not regret not buying Plextor’s PX-708A instead.
