Well the 5-door will be available with the Euro Pkg, and there are a few more tweaks, but nothing major. Those new wheels look interesting, but I can't help but think they don't fit the lines of the car. I'll have to see one I guess.
More specific details can be found in the SVT forum here.
Well for those who like the wheels, skip the trip to the dealer and watch for them to become available through BatInc or Tire Rack. They normally sell the SVT wheels cheaper than you can find them at the parts counter IIRC.
