What are peoples thoughts on US interest rates and the Fed...

What are peoples thoughts on US interest rates and the Fed meeting tomorrow, it seems ever time there a shift in interest rates the market freaks out, this is probably the most anticipated rates rise in many years but for some reason the market always act surprised no matter what the result, I am sure it is just t he big boys pushing the markets around to suit there own agenda, with a new Fed Chair all eyes will be on him as to see if he is Hawkish or Dovish and if we will get 3 or 4 interest rate moves. Any thoughts on how the market will react.
