Mitsubishi's "Wakamaru" robot ready to join the family...What's next?

According to CNN.com, Japan's Mitsubishi Heavy Industries Ltd. unveiled a family-friendly robot that can recognize up to 10 people and call them by name.
"The 100 cm (40 inch) tall Wakamaru will approach and greet family members in a gentle, feminine voice when they arrive home and offer to pass on telephone messages or read out any e-mails that may have arrived. In the morning, Wakamaru will glide to your bedside to wake you up with the news headlines and weather forecast, remind you of your appointments for the day and may even invite you to join it in some light exercise."

Are there pros and cons to this invention? How big is the robot market? What will scientists come up with next?
