Dear God. I wouldn't normally post links to another forum, but the effort put into NeoGAF's official MGS4 thread is just amazing.

It's here if you want to take a look. This will probably be one of the best sources/collections of information on the game, period. Just beware of potential spoilers, though I'm sure they will be either tagged or heavily moderated. The thread is going to move super fast as well. I mean, it was just launched last night, and there are over 1,000 posts in there already.
