Don't be like that. I even made an MGS joke when the trailer was being revealed live on GAF! The character lookalikes can easily be explained as people projecting onto the game. The interchanging logo gif uses a typeface and spacing for "Metal Gear Solid V" that has never appeared on anything official, and it isn't even a perfect fit if you look closely (the letter T in particular). That is to say, it looks like somebody has tried to make the letters fit the logo, rather than the other way around. The spacing itself is variable with different letters having different lengths between them (the V in particular is quite distant from the word prior compared to the others), but shit, I'm not a font expert so I don't know if that's unusual or not.
I've seen people hype up a series of coincidences into what turned out to be fucking nothing what feels like a zillion times, and I've dealt with plenty of people making similar "ironclad" case for all sorts of conspiracies or other such stuff. I'm extremely skeptical by nature. The way I feel right now, this has a less than 50% shot of actually being MGS related.
