Both Engadget and Gizmodo have had some hands on experience with the new MotionPlus accessory for the Wii remote that claims to deliver 1:1 motion tracking. Opinion seems to be divided, with Engadget taking the view that the new accessory doesn't add much that the original remote couldn't already do. Gizmodo are wholly more positive in their first impressions, claiming it finally delivers the kind of motion response that was expected when the Wii first launched. Both sites express concern about the added cost, as well as the fact that a lot of new games are going to make this a required purchase.
