Good catch. You're totally right there. I read elsewhere that it was going to be a Clover Trail chip to help ensure battery life. Turns out that's not the case with the Surface Pro now, although several of the other OEMs are going the Atom route. Estimates for battery life with the i5 processor are a bit low.... in the 6 hour range. The Win8 tablets running Clover Trail have been getting much better battery life, albeit at slower clock speeds.
