Unless these re-releases come with some significant additions, we find it unlikely that even hardcore Kojima fans will be throwing down their cash. Hopefully, this isn't the end of the 20th Anniversary announcements ... we're hoping for a Portable Ops sequel (and some more info on the ever-elusive Metal Gear Solid 4 would be nice too).
[Update: IGN reports that a limited edition DVD will be packaged with the MGS bundle. Also, a new soundtrack CD will be made available. Check for details on the new official website.]
