I was told by two different reps that the Touch Pro on Sprint is going to be the same price as the Diamond ($549.99).
To answer the OP's question:
This is not just an upgraded Mogul. It's more like a Mogul on steroids and extenze (the male enhancement pills)
Quadruple the resolution, quadruple the RAM, flush screen, smaller form factor, 3.2mp camera w/ flash, faster processor, improved UI, alleged "faster" GPS locks, etc..
And it looks sexy.
