I'm not holding my breath, but it would be nice. The cards are stacked against AMD. Intel's process node advantage alone makes me extremely skeptical.
I don't think we should be seeing cheaper quads unless Intel decided to build some without the iGPU component, and shed 60% of the die space used. Intel is not competing against AMD, really, but against their older chips, ARM (Qualcomm / Samsung), IBM, Apple, etc., and they need that revenue to stay ahead of the other giants.
Maybe the way for us to see $100 i5's would be for IBM, Apple, Qualcomm, and Samsung go out of business, and for Intel to cut back their R&D budget tremendously and settle for slower improvement of their CPUs. As it is, each generation is providing huge benefits to performance per watt, and is vastly improving performance AND battery life in mobile devices.
