What's the difference between the LExxR41B and the LN-Rxx8W they sell abroad? I've noticed that they are using this TV, or a Sammy LCD with the same design as the LN-Rxx8W at the Tokyo Games Show with the Xbox 360. Visibly the only difference between this set and the LExxR41B is the speaker grill at the bottom. Does anyone know the differences between the two sets? Does anyone know the exact model number of the set they are using at the Tokyo games Show and how it compares to the LExxR41B?
