On thing that I don't see anyone mentioning is the bigger picture - which is that 2012 was not a great year for business anywhere except maybe the US where it was only decent.
The global semiconductor market in 2012 shrank 3.2% from 2011. The EU is having issues, China had a rough 2012, Brazil is struggling and Japan's economy continued it's long-running issues.

I see people predicting industry trends based on the 2011 results, but it's possible - in fact, I would argue that it's likely - that at least some of the trends were caused by macroeconomic issues more than technological or consumer reasons. In other words, I'd wait for the end of 2013 before I'd call anything a trend...
