I have long suspected that this will be Canon marketing strategy.
Selling body at lower price, gain from the lense sale.
This business model is similar to printer business. We can get printer at very very cheap price, but the ink is expensive. I worked in one of the printer manufacturer before and the engineer told me that it is the ink sale that made money not the printer. Another example is motorized tooth brush. The brush refill is expensive.
Now, if more people can afford dslr, automatically lense sale will be up as people needs various lense for their photography needs.
hmm...but the body prices arent selling any cheaper...:think:
