I think that amp manufacturers really need something new to get people to buy new amps. If you think about, it the amplifier portion of our systems is the one thing that really does not need upgrading. New bells and whistles, surround technology etc. has not really applied to the amplifier - one of the reasons separates are so appealing. The fact that the industry has come up with something 'new and improved' just makes me suspicious until it is way proven.
