Why buying an expensive universal player?

Over the past few years I have noticed that universal players become obsolete in not time. Even ultra expensive machines are sold at a fraction of the price shortly after release (2 years?). So, why expending a fortune in ultraexpensives players? Does not it make more sense to have a good expensive dedicated CD/SACD player that is not going to change dramatically and maintain a mid-priced universal player up to date?
