Bv7-40 mk3 and mk4 has Bsys3 MK2
beosystem 3 stand alone for bv4 are realesed
bv7-40 /55 in 3D are to be realese in july 2011 i think
the same parts (DVE,AVS,DSM) are different in bv7 (i am not sure if it's possible to have the old panel in bv7 with new bsys3)
bsys 3 MK3 have HDMI instead of DVI outputs
