I will inform on the release date on the same day trust me!;)
B&o are going to do a 25p update instead of 24p in the new firmware 4.2. Because the existing panel can only handle 50Hz pal/60Hz ntsc. So the new firmware are going do duplicate the 25p with x2 = 50Hz for a more smooth and seamless picture in pans and fast moving objects to maintain the focus and resolution. So you are only going to miss 2 fps (frames per second) witch is impossible fore the eye and the brain to see..
A second possible thing they are considering is to take the 24p incoming signal and then interpolate it with 4= 96Hz and then divide it with two = 48Hz.. (2 frames missing also)
I think this update are going to be very good!... Not only when you are going to watch Blu-ray HD 24p material but also on DVD and DVB broadcasted movies.
