Alternate architectures are not going to do much to dent the two generation lead in process.
IoT and Wearables mean nothing to Intel, there is not enough money there. Mostly a marketing effort to signal to their investors they aren't going to miss the next big opportunity like they did mobile. Of course that ignores the fact that Intel was never going to be much of a player in mobile. All the money in mobile is in the base stations, not in the handsets, and Qualcomm (3rd largest semi conductor company behind Intel and Samsung) completely dominates the IP in that market. What matters there is radio technology, not microprocessors.
