I just found these pictures at militaryphotos.net:

You can clearly see from these photos that the US F-22 and the Russian PAK-FA are dramatically different aircraft.

As as aside, militaryphoto.net is a very decent place to get some good discussions on military topics. Unlike so many other fora, the jingoistic flag-waving trolls usually get rapdly denounced because a lot of competent folks post there.
