the water cool engine will on ever Harley by 2010
expect the 1200 cc motorcycle
thats not rocket science its the way it is because of EPA
Doubtful given the investment in the 2007 96" Twin Cam engine.
I personally believe that there will always be aircooled models available, no doubt with larger displacement engines with restrictive catalytic mufflers and other eco friendly devices to meet EPA regs.
H-D is a company steeped in history and tradition. Remember it was their back to the future designs that brought them to the forefront of the heavyweight motorcycle market. The Softail Heritage, The Road King, The Softail Deluxe , The Softail Springer and The Heritage Springer. No doubt at some point they will offer a big water cooled bagger, but look to the V-rod line to expand fiirst as Bill has already detailed in his link below.
