There's nothing saying canon WONT introduce either option. It's still early and so many things can still change up until the day it is released.
It is very, very unlikely. Canon does not even produce IR or astro camera at this point and has shown no interest in moving outside its comfortable mass market devices. Photography oriented cameras without a CFA pretty much exist only a niche products at the high end (I think the cheapest one I have seen was 12k for the digital back alone) as MF backs, and I have not seen one in a DSLR package since the Kodak 760m.
Conventional marketing wisdom says there is not enough market for them and that software conversion is 'good enough'.. and Canon is not really known for taking risks or serving niches at this point.
So while I agree it is, in theory, possible, and I would love Canon to introduce such a camera.. I do not see it happening. Which makes me a sad panda....
