Sony Ericsson Xperia arc and Xperia neo handsets. These are currently $350 and $300 unlocked at Newegg, respectively, so they'll be a good deal when they get updated to ICS. We just checked those two at the PCRB, but probably the rest of the Xperia pack has been submitted too.
The company has said numerous times that it has learned its lessons from past Android mistakes and is now working hard to update all of its 2011 lineup to ICS - some say in January, some say in March.
This should set a precedence for other phone makers, as Sony Ericsson simplified its own Timescape UX in order to achieve easier updates, and is apparently ready to deliver ICS to its flagship 2011 handset - the Xperia arc - in a timely manner. But let's not get ahead of ourselves before the update has hit the handsets.
