All that is really up to you COPhotog, I'm not sure Canon isn't meeting "Market's demand", or yours specifically.
I for one have a 40D, that I purchased in March 2009, and it has paid itself MANY times, I purchased a 70-200 f/2.8L IS II USM last year in March, and it has already paid for itself. Now, that being said, sure, I wouldn't mind a new body with new features, and I'm start to think it might be time to get a 7D, but I don't think that it's impossible for me to take very nice shots with my 40D, I don't shoot with it and always think, gees, I wish... I just go out and shoot
I look at the new Canon EOS 1D-X camera, and the web server functionality, would be very useful for my kiosk operator as I'm out there taking shots in an arena that has 3 rinks, the operator could download my pictures as I'm running between rinks.
Now if you think another manufacturer is offering exactly what the "Market" wants, or more specifically what COPhotog wants, and you can't live without, or whatever reason, go for it, and don't look back.
