See the trouble I have believing any of those days is you have potentially 5 camera bodies being released in 2012, and four of those are major bodies (1D, 1Ds, 5D, 7D).
Canon is not going to do that, earthquake delay or not, they won't stack up 5 major bodies for release in a year. Just imagine if there was a common thread issue that messed them all up, or sales/support was overwhelmed with the deployments.
No, I can't see that happening.
