Looks like Konami isn't going to release MGS4's substance anymore.

[bugrimmar]

MGS2 released 11/12/01, Substance released 12/19/02 - give or take one year in between.

MGS3 released 12/16/04, Subsistence released 12/22/05 - give or take one year in between.

MGS4 released 06/12/08, and almost two years later, still no announcement of a "substance".

Sad.. I was really looking forward to a re-release.
