You probably won't see anything on their 16nm node until some time in mid to late 2015 and it should be pointed out that it is not a real node shrink but instead a fake one where they use the same 20nm node but have introduced FinFET. While this gets them increased energy efficiency it does not give them the other benefit of a node shrink (increased transistor density) and so that means that means there will be less chips made per wafer driving up the cost.
