Yeah, I also thought that ~17W is ULV, 35W is a lot of power for a small laptop. 
The Ivy CPUs are supposed to have a programmable TDP. They might be able to stick a 45W in the 13'' MBP and throttle it so that things don't blow up. But that would probably be a waste of money, and difficult from a marketing point of view...
