Nobody ( here on this thread ) has taken into consideration the Nikon D300S replacement.
Not since the first page anyway... :-)
But you're right. The 7D (& the forking of the "prosumer" lineup to 7D & 60D) was basically Canon's response to the Nikon D300 (the 60D could be seen as a response to the D90) & the demand for a more professional crop camera. In a way, ever since the D3 and D300 came out Nikon has been calling the shots on what the market segments should look like, & it's been up to Canon to try to beat them at their own game. It certainly took a while for them to react but I think that with the 5DII and 7D they were pretty much there, & they'll certainly continue that strategy for quite a while longer. The industry is just on the tail end of the recovery from Fukushima, the banks breaking the economy, and the Thai floods; no one can afford a shakeup right now...
...Which is why they're both scared of Fujifilm. Right now, the X-Pro 1 is the smallest, least expensive, and sexiest camera with wedding-photographer grade image quality, and Fuji still has plenty of other tricks up their sleeves to roll out over the next year or so. I wouldn't be surprised at all if in a year's time we have a Fuji camera in the same size class and price bracket as the X10 with image quality as good as the current 7D.
