It seems like Canon lacks imagination. Even the C300 could have been so much more. They could have hit the ground running with that camera but instead they chose to craw into Hollywood with features already available from other manufacturers at a cheaper price.
So they built a camera for which there is an established market and undercut those already present rather than risk bringing something to market for which they're not sure if there is customer interest.
To me it sounds like Canon executed a good business plan.
Like the new 5D Mark III, the C300 seems outrageously overpriced in this market for what it brings to the table. There's nothing in the specs that looks to the future. Instead everything seems to look to fixing what wasn't there from the past. That's why I say Canon lacks imagination.
You are not the only person that is critical of Canon in this area.
At this point it seems like Canon's strategy is to make us another 2-4 years to add something simple like USB 3.0, add another $500 to the price tag and call it the 5D Mark IV.
This is my fear too.
IMO, the 5D Mark III is overpriced for no other reason other than Canon thinks they can get away with it. Nikon took a more realistic approach with the pricing for their D800 and it seems like they care more about their customers than trying to milk them with minor overpriced upgrades.
I'm somewhat puzzled by Nikon's approach to pricing of the D800. I'd really like to know how they kept it at that price when it should have gone up.
I suspect they're doing one of two things:
1) selling with a really really low margin
2) using it as a loss leader for more lens sales where they turn a profit
... both of these are to try and (re)gain market presence that they lost to Canon with the 5D Mark II.
Of course it could just be that they're getting a better deal and their costs are significantly cheaper than Canon but it is hard to imagine that unless a supplier (such as Sony?) is also reducing the margin on the sensor it is selling to Nikon to help Nikon displace Canon from #1 or just generally disrupt the marketplace in a way that gets people thinking about alternatives to Canon.
