TR's got their IDF coverage summary posted. They're saying the "theme" of this year's forum was performance per watt, & judging on the coverage I've read thus far, I'd have to agree with them.

"Not only did Intel announce a new, common processor microarchitecture that promises higher performance and lower power consumption than the current Pentium 4 and its derivatives, but the CPU maker also outlined a broad range of initiatives for reducing power consumption while boosting performance."
