Replaying MGS2 I realised that we might not see an adult Solid Snake, but we could see an adult Solidus Snake and a child Raiden.
He says that during the 80s he raised Raiden to become "Jack the Ripper" in Africa.
Slowpoke, yeah.
EDIT: BTW, god damn, Solidus is way underutilized on the MGS saga. It's one of the best characters.
I honestly don't think we will, as you said, he raised Raiden, not Big Boss.
I think it's more likely we will at least see a young teenage Solid Snake, at the very least when Big Boss rejoins Foxhound as their Commander.
They (Kojipro) may as well fill the gap because, well, you know... It's the last MGS and it's the only real significant gap that we haven't witnessed yet.
When interviewed Kojima was asked if Solid Snake would feature in MGSV, he replied with the biggest, most cheesiest smile, that he didn't want to say because it'd spoil the fans.
Then again, he says it's his final MGS, then proceeds to say that he's not done with Solid Snakes story yet even though, we know there's next to zero chance we will get a sequel to MGS4. So naturally that leaves us to come to the conclusion that SS will be in MGSV.
That was more than enough to make me apart of Team A (Hayter will be Solid Snake)
Considering he's the youngest LET, I really doubt that. Hopefully we do see child soldier Solidus, whos accelerated aging makes him look like a teenager.
Solidus wasn't apart of LET was he? I'm pretty sure LET was just Solid and Liquid I.E. The Twin Snakes.
Solidus was a separate experiment, if I'm remembering correctly that is.
