A few weeks ago, someone posted here about how Canon ought to be more like Apple. They referenced an article that said Apple was willing to cannibalize it's own business at times in order to grow their business.
It seems that is exactly what Canon is doing and I'm actually quite impressed with their courage. They are taking some risks here and I wish people would acknowledge that, since Canon is often criticized on this forum for being too conservative and too formulaic.
Although I don't ever expect to be in the target market for this camera, I find it very exciting because of what it means for the future of DSLRs. Frankly, I don't think we can predict what direction Canon will go next. Will they use the 1D X sensor in the 5D? (somehow I doubt it.) Will they release a 1D S (studio) that emphasizes resolution over ISO? (very possible in my opinion).
What features of the 1D X will show up in the next generation of 5D and 7D? Will they produce a pro-level APS-C body aimed at wildlife and sports shooters to replace the 1.3 crop and add more reach from their lenses? (also very possible in my opinion).
All in all, I think this opens up all sorts of interesting possibilities and I'm anxious to see what materializes over the next few years.
In the meantime, thanks Canon for making things interesting. I honestly didn't expect it.
