Team: Would love to get your thoughts on this. Redfin has just rolled this out as well.... Cost would be about $200 per listing instead of the $150 you pay for current pictures..
Press release from 8/21/14. Right now it's Seattle only, but they say they're rolling it out to the rest of the country in the coming months. http://www.redfin.com/about/press/releases/REDFIN-ROLLING-OUT-MATTERPORT-3D-TECHNOLOGY
Here is an actual listing that had the 3d tour (now pending). Scroll down a bit and check out the lead generation right next to it. That looks like a pretty powerful hook. https://www.redfin.com/WA/Mercer-Island/5310-90th-Ave-SE-98040/home/256168#3d
