Every year Canon launches a new Rebel body, so 2013 we can expect a 700D. Could Canon conceivably launch a 70D + a 700D at the same time or even in the same year? Maybe they could, but I sincerely doubt it. It would be like BMW launching a new 5-series as well as a new model the 50-series in the same year! Even the marketers are not that dumb 
edit: it would be like Coca-Cola changing Coke Zero, and then launching Coke Hero (a new product) around the same time
You seem to disagree with yourself.
If Canon launches new Rebel every year
AND
sometimes (but not every year) Canon launches a higher level body
THEN
in the year when the higher body is launched there is also launched a new Rebel
SO
it's in contradiction to your doubt
THAT
they shouldn't be launched in the same year
SO
not Rebel every year
OR
no higher level body at all
OR
there must be some years (higher body launches), when they are launched in the same year

As someone who is not a native English speaker (I understand you're Polish), you did not understand my simple logic, so I'll make it even plainer:
(1) Each year Canon typically launches a new Rebel body - so in 2013 we may expect a new 700D (T5i)
(2) Canon DO NOT typically launch a 40D, 50D, 60D......70D (xxD model) each & every year - so once cannot say for sure that one is definitely expected in 2013
(3) It just so happens that 2013 is a year that a replacement for the 60D would normally occur, but to call it a 70D and simultaneously launch a 700D would be too confusing (coincidence that model numbers may conflict)
What I said, in clear concise English was it would be a marketing disaster to attempt to launch 2 new products the same year with nearly identical (except for one zero) model numbers.
...btw P-R-O-V-E-D is how you spell 'proved'...and you actually proved nothing other than trying to be clever...and you did not do a good job at that.
This is a forum for Canon aficionados who are seriously interested in what new products are coming down the line and what the model designation that Canon deem fit to call them e.g. the new 6D is a good example. The 7D is also a model that is due for an upgrade (7D will be 4 years old in 2013) and there are rumours that the 7D2 and a 70D might be merged to create a new King of the Crop Sensors -> this further validates my argument that Canon may be cautious about releasing a new product called the '70D' for the reasons mentioned above. What really matters is what additional features this new flagship crop body will have.
