My statement was 5 fps or better so if they could go 10 fps, all the better. Works for me.
I get the glass investment -- may not seem much but I have about $3K right now in glass due to costs of insurance etc. That is more than the $1,900 body. But, I plan to keep 7D regardless if I change brands.
But, if I was going to invest $8K for a body and go to D4, one does that before he continues to invest too much in glass so I think we are on the same page. What I have now, I am happy with.
I still think Canon is likely to bring to market new bodies by August/Sept that I will like. I also have another application that is work related that I can use the 7D for given its remarkable 200/300/400/500/600/800mm glass capabilities. For that purpose 1.6 crop factor has value.
So, I am not unhappy with Canon. I just want to see APS-H stay in tact and improve in that direction. Hopefully, meeting the specs I laid out. All in all, I may break down and get an EOS 1D Mark IV for now so we'll see what August brings.
I also just read that in test, the 7D did better than Nikon D300 with noise overall.
