I want to know the answer to the following question:
Who was the President and CEO of SCEA in the year 2010?
All the background I'm provided with is that "PlayStation Plus (commonly abbreviated PS+ and occasionally referred to as PSN Plus) is a premium PlayStation Network subscription service that was officially unveiled at E3 2010 by Jack Tretton, President and CEO of SCEA.". Is that enough to answer the question?
Answer: yes
