"Watson can understand unstructured data, which is 80 percent of data today: all of the information that is produced primarily by humans for other humans to consume," according to an explanatory video about IBM's Watson tech.

Watson's knowledge of context and social cues could help Pepper better understand language and gestures.

SoftBank and IBM envision Pepper as a teaching assistant or nursing aide, or working in self-service and retail environments.

A launch date hasn't been set, but expect a lot of interest. Since Pepper went on sale in Japan last June, it's sold out every month.
