Isn't this strange? We know everything about the new 5D, 24-105 f4L IS, but nothing
about 1D MkII N. It might be a sign of two things - very tight secret, because
it's so great or there is nothing to talk about, just minor tweaks.
How about 300 f2L or 200 f2L rumored a while ago? What do you think?

It's either a secret Canon is still holding, or something that is not gonna happen.

I would say it's "not gonna happen", EXCEPT for the fact that the leaked 5D PDF file had the 1D-II N mentioned in it.
