Stale link by now, but: The new Aibo pet robotic dogs will sell for $1500 in the U.S. The new model "has an array of new features that enable it to experience 'intimate interaction with people,' Sony said. ... 'From the first day you interact with Aibo it will become your new companion,' a Sony promotional video said as several new Aibos were shown cavorting, waggling their ears, and avoiding objects in their path."
