Well, the frequency with which Canon customers or potential customers complain about Canon "crippling" or otherwise shortchanging their products is a clear indication that they want more for every dollar. Canon hasn't thus far been willing to respond to all those demands for more/dollar...until they do, your going to keep hearing people complain.
It's become a simple fact that you can often get a LOT more value with other brands than with Canon. That's not to say that Canon doesn't make a good product...but their products are increasingly not providing what their customers demand. Some simply jump to another brand or add another brand to their kit. Others complain. Hopefully Canon will change in 2015 and actually start delivering.
Those are the ones Canon will actually listen to. Canon listens to dollars, no vents :-)
Which is why I'll be spending money on Sony next year and not Canon. Voting with my feet and/or wallet. Had enough of being jerked around by Canon.
Well if you're already waiting for next year anyway, why not afford Canon the chance to show their cards if this CR2 pans out? Ya never know. They won't stay behind forever. I'm not saying it will deliver everything per se, but if you're already heavily invested in Canon glass, why not sit tight on making a decision for something you don't plan to do til next year anyway?
And that's exactly the outcome the planned release of rumors like this aim to achieve. (Which is to say that I don't believe that all rumors are leaked and that a good portion of them are marketing, sometimes even defensive marketing.)
The real point here is I don't need to wait for Canon to show their cards - I know what Canon will do simply by looking at what they've done in the past: the minimum required so that they can entice me into buying the next model with a fuller feature set. I'm sick of being treated like a dumb and ignorant consumer by Canon.
I'm sure that Sony will bring newer models to market in 2015 and that they'll be streets ahead of whatever Canon debuts with. Canon is playing catch up. Why would I want to continue buying into a company that believes that "catch up" is "good enough"?
To answer your question, with another question: Is this rumor enough to stop me from buying Sony? Nope.
