@ samuel, the MGS bundle was the 80GB one
also, I am not sure about the MGS bundle, it is not even listed on play and there is not a gunmetal grey bundle in europe
These are what I think the bundles are:
Japan:
Coloured 40GB with DS 3, Sixaxis and MGS 4 (100k avaliable only)
Gunmetal grey one (sold out from Konami.jp)
North America:
Gunmetal grey
MGS 4 + 80GB
Europe:
