I don't see how announcing a 7DMKII or big MP camera would hurt year-end sales for Canon. These are going to be expensive cameras and for a different market than say a 70D. The 7DMKII is going to be the cheaper of the two. But even that's going to be at least 2x the cost of the 70D.
But man.. That 7DMKII is getting so much hype... It's going to have to be a 1DX in APS-C format to satisfy people
If Canon wants to introduce new tech, they'll do it in their premium (crop) camera and set an according price tag - also some Canon top exec recently stated that they want the 7d2 to be make a big splash.
Concerning the thread: Obviously people have lost faith that the long-time vaporware products like 50/1.4 + 50/1.2 mk2, 35/1.4 mk2 could actually appear :-o ...
... but my money for a 2013 release is on a new 430ex2 successor with rt.
