Avatar - Changing Hollywood and Advertisements?

Avatar comes out on December 18th and will change the way actors
perform in movies forever. It's going to be awesome and I can't wait
to see it. After watching how they made it though, it made me wonder
how long it will fake to see this live performance capture being used
for commercials too. Once the technology catches up price wise to
where Cameron brought it, it should be more cost effective than
shooting a regular commercial. What can we expect from commercials in
the future? Maybe after I see what they have done in the movie it will
be easier to see the possibilities for advertisements
