If u speak to a good dealer the products have largely been upgradable anyway. Obviously anything with a Beosystem 2 or 3 - especially the 3 - is easily upgraded with a new panel, but in addition to that we have done loads of upgrades of BV4 and BV5 from non HD to HD panels, including adding 2 HD inputs to the Bsys2 based ones. We almost always upgrade the panels on used Bv7-32's to the latest version to get the best possible picture quality, sometimes 7-40's and BV6's too. Anyone with a 7-40 can simply upgrade the panel to a Mk5 or Mk6 3D by just upgrading the screen and keeping stands, speakers, accessories and remote etc. I can't think of a more upgradeable tv brand? None freeview sets can be fitted with freeview modules, some non HD sets can be fitted with HD modules, sound modules can be updated.......
With the 12-65 being Bsys3 based you can just upgrade the panel to whatever, whenever you like!
