Where is everyone?

On the 10 or so servers in the server list theres maybe 50 people total during prime hours in Europe. After that it falls off to no one being online until the next day. After the last patch the game is really much more playable so where is everyone? 1946 is good and all but after playing CoD I cant go back to that, is it possible no one is making the switch simply because 1946 has much more content and can run on peoples pentium 1 machines?
