Update: I e-mailed the editor of PSW and asked him to confirm that this is true, and he replied that a Konami Rep confirmed that the build they played will be on PSN sometime in relation to the games release. If the game stays on track as Konami has said so far then it should arrive around Feb as the magazine states.
A journalist decided to e-mail the PSW magazine editor who indicated that a MGS 4 demo will hit PSN next month. The editor replied by stating that at the time of writing the article a Konami rep told PSW that the demo they played in the office would be appearing on the PSN store.
However the release of the demo could depend on the game's actual final sale date but February is very possible.
To quote: At the time of writing the article a Konami rep told us a demo, the demo we played in our office for the magazine article, would be on the PSN Store.
It's finished, we played it, so something should be appearing this month. It could all depend on the game's final on sale date, if it has moved to May then a demo could appear later, possibly February.
