There have been 4 haven't there. Well 5 if you include difference between matte and gloss black.
black, silver and white.... and the nice grey one above.
The silver I think was part of a limited Japan bundle (I could be mistaken on this one) the white is still available as far as I know. And the grey one for MGS4 was a limited Japan and US bundle, I don't remember seeing it here so it may not have released in Europe.
