Canon is in the business of mass production, they want to produce millions of products that they can sell worldwide.
I see the large high powered strobes as a small and specialty market. However, with competition heating up for sales, its entirely possible that Canon could purchase a strobe maker and market it through their huge sales network. The specialty manufacturers often struggle trying to establish a world wide presence but Canon has it in place.
Canon has said that they are looking for businesses to buy, but they also said that they want something not related directly to the cameras they now sell.
