2.0 is an optional specification. Announced? Oh, a year or so ago. PS3 seems to meet 2.0 already, but it's not advertised that way. Maybe they need to turn on a software switch to enable online access during movie watching. But it has the persistent memory and the ethernet connection.
My guess is, a year from now you won't see any profile 1.0s left, and probably very few that don't meet 2.0.
I believe the first 1.1 media is released in January.
