The first arm chip they sell is relatively low capital cost version to establish a foothold in the market, and maybe get software and everything else prepared for their real goal with their inhouse arm core, in 2016. So they might sell it at price that is reasonable for its performance level, assuming they have prepared and much higher performance arm core in pipeline coming in 2016 that they use to lift the price.
