Nobody who knows what they're talking about would say that. Giving a 20Mpx crop sensor the same ISO noise capability as the 6D would have required a truly revolutionary sensor, and NOBODY has one like that available. At least not for a price that anybody who's not building a space telescope could afford...
I don't think any rational 7 d owner was expecting 6 d iso performance equivalence - what would have been real good is a genuine one stop lift in iso performance and / or with better detail in the shadows and I don't think that was an totally unreasonable expectation really after 5 years of r&d for canon - so a 22 mp or maybe a 24 mp sensor with better iso performance and no 7 d c noise banding and some better detail in the shadows seems a pretty reasonable hopefull expectation and I expect I was not alone in that hope
if that's is in there with the "all new 20.2 mp sensor" (canon marketing speak) that would be brilliant but it appears that may be unlikely based on the samples shots out there but no one except cannon and its paid marketing photo people know that answer yet - so probably somewhere close to the 70 d iso and in shadow detail performance will be the actual go
so good enough to shell out $1800 if in usa or $2300 if in aus for the new 7d mk 2 crop cam with a super 65 point cross type af and with cp at f8 capability and gps etc etc well I guess it will have to be because that's what it is and it aint going to change for awhile I imagine !!!!
