All that hype is ridiculous. Of course, there will be new processors in the future, what surprising about that ? In the 2000s, performances were DOUBLED every 18 month, for the same price, and nobody found that astonishing.
It's not ridiculous, its makes complete sense. It's because for years we didn't get shit. Intel kept/keeps releasing basically the same CPU with minor gains. In the 2000s we were accustomed to those doublings. Currently we are accustomed to the minor gains. AMD breaking that status quo has lead to the hype.
Most of the performance increase also seems to be from scaling out cores so there is little you're losing by buying more cores now. Of course things will get cheaper and slightly faster.
