Before we start getting into the entire Canon vs Nikon debate, for full disclosure, do you plan on upgrading once a 70D and or 7D m2, or 5d m3 comes out? Or are you just floating a hypothetical out there? I my opinion, I think Nikon over the last few years have had a slight advantage over canon however over the last maybe 2 years canon have made great strides to narrow the gap, and in the 7D vs D300s, surpassed nikon in many categories. If you're not fully satisfied with the 60D, consider our options and do whats best. Also consider lenses and cost of switching over. Only you can answer that.
