I spent a lot of time at Panasonic's CES exhibit and viewed their demo of the new 2010 Infinite Black dedicated demo room. They had the Infinite Black directrly next to the current V10 in a almost totally black room. Both panels looked very good, but to my surprise I liked the current V10 pq better. It had more detail in the image and the black level was extremly close to the 2010 Infinite Black model.
I'm at the show with 2 of my kids and we're working on uploading all of our photo's so stand by for the link.
