If they were going to have a 20nm processor, they'd have been shouting from the rooftops about it, just as they were with the modem, IMO.
That being said, Qualcomm's 20nm modems will probably make them a mint, and while I am now convinced that Moorefield will be the winner, I think Qualcomm still gets one more year to really "own" the smartphone market.
And, hey, if all else fails, QCOM still collects a royalty check on every phone sold...
