Very possible, however other than that hospital scene we've seen nothing of Ishmael since. Now it's more than likely that Ishmael is a character and Kojima is simply withholding info on him, I personally don't agree. Just differing opinions really, there's not enough info to say 1 way or another yet.

But canonically, who could the character be, assuming you're right and he's a returning character. We'd have to assume it's someone in a game set previously in canon, so we have MGS3, PW and maybe PO (genuinely don't know whether it's canon or not).
