While that's undoubtedly a very stunningly low price, and will appeal to many, the Sharp TVs are a long way from being the be all and end all of video performance. So, people wanting higher performance will still buy higher up the tree, but how high? I don't think, personally, it's easy to reconcile paying 5 times as much for an OLED panel from LG with a few Beovision goodies tacked on. And panel tech changes so quickly still, hard to keep up for a niche company like B&O.
Back in the day Beovisions made more sense, because in addition to the integration with B&O gear they offered improved picture quality over the donor panels they were based on. The B&O video dudes did good work, when I bought my first plasma the Beovisions offered a fair amount of an improvement over the Panasonic panel they were based on. Fast forward to today, and things are different and if anything the price delta appears even bigger.
But no doubt B&O has a challenging future.
