You can't say it's basically confirmed. It can never be 100% confirmed until the game is released or Kojima confirms it. For all we know, this will be like 95% likely and then Kojima will reveal it's some new character, and undo all these links we've made. We can't confirm shit.

It's speculation. Will always be speculation until any official confirmation from Kojima.
