This loose theory may sound crazy in some way, but please bear with me on this, as this is based solely on the MGS4 trailers I've seen so far. Also, someone may already have posted these kinds of thoughts in the community, but I didn’t see them, so this is all new to me! :D

That young Snake at the end of the latest MGS4 trailer... my opinion here is that he's the real thing and Old Snake is Big Boss who somehow survived and wants to make things right or bring on the ultimate duel against Solid Snake... I mean consider the following:

1) Old Snake has the knife and gun (Rifle in this case) CQC stance in this recent trailer just as Naked Snake had in MGS3. This is the only reference we can get as far as CQC skills go... never have we seen this in previous MGS installments, so I think this would be a major giveaway.

2) Old Snake gets picked up in the chopper in front of what seems to be the Boss's grave. That grave scene before the chopper arrives looks too familiar to the end scene in MGS3.

3) If you compare Liquid Ocelot and Old Snake's looks from the MGS4 trailer and go back to compare them to Naked Snake and Ocelot in MGS3, you’ll notice that they seem to be in their same respective age groups throughout the timeline of both games.

4) Old Snake sticking a gun to his mouth in the first trailer: you'd think it's Big Boss having a hard time coping with the fact that his ''Outer Heaven'' is a major cause for all this craziness. I mean why would Solid Snake ever think of doing this since he’s not the direct cause for all this?

5) All this dialog from the first MGS4 trailer such as ‘’War has changed’’ and other said details from Old Snake are the kind of sayings you’d get from a real War Veteran such as Big Boss. In this trailer, he seems to reminisce from old War combat experiences in a way Solid Snake could not have experienced in his day.

Basically, MGS3 was an obvious effort to point out who Big Boss really is and how he became the character we all know and hear about throughout past MGS games. That being said, it may also serve us to better understand Old Snake in the MGS4 trailers.

I want to dig out more to prove this theory better, but just by looking at that last awesome trailer, I'm more and more convinced that this it! If this is the case, we’re in for a sweet masterpiece of a game!

Anyone out there think I'm not crazy... please?! :shock:

I would greatly appreciate anybody’s input, comments and or suggestions on this!

Cheers!
