New tidbits about Canon's 2013 announcements showed up, both here and at Canon Rumors. But not exactly the same tidbits.
Let's start with the EOS M. CR is reporting that
[...] one of the announcements will be to introduce a second EOS-M body. The body will be slightly bigger, and have a viewfinder. They will also introduce at least two new lenses with the body. I’d expect a telephoto zoom and a fast prime.
I have no information about a new EOS M mirrorless camera, my source told me that there will be new EOS-M lenses. Apparently Canon wants to see how well the EOS M is doing before releasing a more pro oriented body. I also got word (earlier) about two new EF-M lenses, but my source was referring to fast primes, a 35mm and a 50mm (f/2.8).
Next, the EOS 7D Mark II. Both here and at CR we got word that Canon will announce the EOS 7D Mark II before end of Q1. In addition I have been told that Canon will also announce the EOS 70D and a new Rebel (possibly the successor of the EOS 1100D). Three new DSLRs in Q1? Possible. No EOS 7D II specs.
Finally, the mighty big megapixel DSLR (~46 MB). While I have informations suggesting a Q3 announcement, CR is reporting a Q1 announcement, quoting:
The 40+ mp camera gets another mention and we should expect an announcement in Q1 of 2013. The camera will be physically bigger than the 5D Mark III, but will be smaller than the EOS-1D X. It’s noted that the sensor is currently in EOS-1D X styled bodies.
I am rather confident there will be new EF-M lenses, and also about the new DSLRs. And while I have been told Canon is testing the big megapixel DSLR, it could take some more time to get announced.
