Personally, I don't think we're ever going to get a straight answer about who the G-Man is. He is simply an enigma without an explanation. Even if everything else is finally explained, I don't think G-Man ever will be.
I don't think the G-Man is simply an alien from yet another dimension. He's far too powerful and far too mysterious for that to simply be the case. So much mystery has been allowed to build up about the G-Man, that simply calling him an alien would be a little too easy. We've already killed so many aliens in the game, what makes another one so special? Instead, I think that the G-Man is something of a deity, not really a living being, but something else entirely.
Of course, so far, the only thing I've really seen that is even possibly pointing this way is the shot of the G-Man on the television screen in Anticitizen One. As you can clearly see, there is a large black bird on his shoulder.
This leads me to believe that the G-Man is in fact the Raven, from the mythology of many Native North American tribes. In their mythology, the raven is either the creator of the world, or acts as a messenger, advisor, or as a sort of a guardian. He is neither a hero nor a villian. Instead, he's something of both. Whether he created the world or not, he still interferes in it a lot, guiding the world in the direction he sees fit. On top of this, he also has the ability to shapeshift into human form and whatever form he wants. The line where "he doesn't seem acustomed to human speech" doesn't necessarily mean he's an alien in disguise.
Anyway, that's just my theory.
