agree. they are too conservative. I still remember when Canon first launch DSLRs, Nikon was (speculated) still observing the market and far more behind than a lot of companies. Nevertheless, over the years, Nikon has taken over their shares in DSLR market. I wonder is it because of their strategy or they always "finally" realize what went wrong. However, some companies which were making much more better have been taken by other companies as well e.g.: konica & minolta.
now its Canon who is being conservative... they are still doing a "wait and see" before launching their (rumored) mirrorless system (if they do launch it at all anytime soon). Nikon is faster for this one.
