Good point i wonder if the 2011 tvs will receive the updated apps that the 2012 sets will boast?? The place to keep an eye on is the App market section of viera connect for these, for example, a 3d app was recently released here and although it's just moving images of museums, a few short movies, some footage of Nasa and some concert footage of Elbow it's a welcome addition and free 3d content after all.
Here's hoping that the likes of Netflix arrive soon as i can't see any technical reason why it shouldn't happen, it's just an app after all.
