The retail for 60D will be $1099.
Looking at the spec, it appears that 60D isn't really a successor to 50D, but more as something for those who wanted HD video but not T2i (and to compete with other company's video capable models). Then again, 7D probably was the real successor to 50D. I agree about the plastic body, but I think Canon's trying to position it as uber-Rebel more than traditional xxD model (it even uses SD instead of CF now).
