I have talked to my dealer in Malmö and he showed me this information from B&O:s internal web:
About the new BV4: This TV with the new D10-panel will support 1080p/24fprs. And the Beosystem 3 will get a new sw 4.2 which will support 24fprs-incoming signal. This means that the new BV4 will fully support the new Bluray standard.
About BV7-40 mark III: If we upgrade this tv with sw 4.2 it will also support 24 fprs (bluray movies) but it will NOT support 24 fprs on the screen, which means that the 7-40 has to make a 3:2 pulldown anyway and the "jerking" picture is still there. But maybe the Beosystem will make the 3:2 pulldown better, than an average bluray player. What I mean hear, is that if you buy a blurayplayer, put it in a 1080p/24-mode and let the BV7-40 convert the signal to 60hz. I will test this as soon as I have implemented the sw 4.2 in my Bv 7-40. But I think that B&O will during this year upgrade the BV 7-40 to mk4 and put a new screen which will support bluray movies all the way.
Software 4.2 will be released "soon" according to B&O. I think it will be very soon, because the new BV4 will have this software as soon as B&O start to deliver it to customers.
This information is from B&O and I hope this clears things out.
