Just a quick link to a very interesting read on the top 10 risks for 2011.
For me it is risk number 7 that stands out as my sleeper for 2011, particularly in the financial services sector and any other sector where there is a strong feeling of stability because of history. Non-traditional entrants tend not to concern themselves with the limitations but rather work on alternative models to penetrate these markets.
Any industry that feels invulnerable to a new entrant to me is the most exposed industry.
That is just my humble opinion but look at history, at all the times countries or organisations have thought they were impossible to touch (ie. WWII and the USA, Sony and its portable music business, the airline industry, etc).
