As far as I can tell what they are saying is that during the transition period to new technologies there will be a situation where new technologies will not improve and will fall back a little in the area of performance.... which is to be expected. As that new technology improves it will again march reverse and performance will improve. In other words - if power consumption is important to you you will make the leap to the new technology first. If performance is important you will stay with existing technology in the interim. Performance improvements for existing technology is reaching its max, so there will be a stall or slowing down of improvements. That of course was not as interesting so they just spun it to get more readership.
