I am semi-fluent in Italian and have personally translated these points myself from the pictures in the link.
Other native Italian speakers have also verified these points.
General
- Avatar creation is for the online elements only.
- The are 50 main missions.
- Quiet leaves you after mission 43 and to finish her story you will have to find her after the main one is over.
- The last mission is against the Metal Gear controlled by "The Third Child".
- Quiet goes to the hospital to kill Big Boss and speaks while doing so.
- The "man on fire" is Volgin. You have to get recover his body in Chapter 2.
- The guide says it's safe to assume that Eli is Liquid Snake.
- The alternate name of the ST-84 Metal Gear is confirmed to be the Sahelathropus.
Big Boss/Ahab
- The guide strongly suggests through clues that the Medic from Ground Zeroes is the version of Big Boss who awakens from the coma in the hospital. This version of Big Boss is know as Ahab.
- The guide notes that Big Boss and the Medic have similar voices, so he is a strong candidate for being the version of Big Boss/Ahab that awakens from the coma in hospital.
- The guide also says that the Big Boss we see on the operating table in the "Don't you die on me dammit!" scene from the trailers does not have shrapnel in his head. The guide suggests that the Medic is the person to mostly have the shrapnel in his head, while also being the same hospital room, as he protected Big Boss from the Paz's bomb blast in the chopper in Ground Zeroes.
- The guide says that the version of Big Boss/Ahab that awakens for the coma in hospital has a DNA test done with Eli. Their DNA does not match. The guide goes on to state that Eli is a clone of the real Big Boss, their DNA should match, which again gives a glue to Ahab's identity.
- The guide notes that when Eli asks Ocelot where his father is, Ocelot replies that "Your father isn't here". This is despite the fact that Ahab is watching their conversation behind a two-way mirror.
Ishmael
- The guide doesn't say who Ishmael definitely say who Ishmeal is. Konami and Kojima Production asked Piggyback, the creators of the guide, not ti reveal it. Ishmael identity is revealed in an optional mission after the main story has ended.
- Huey is not sure of the version of Big Boss/Ahab's identity when he first meets him.
- It does however, go over some fan theories and gives clues towards the true identity of Ishmael.
- The guide discusses the theory that Ishmael is imaginary. It says that this can't be the case as Quiet sees Ishmael when she comes to assassinate the version of Big Boss/Venom Snake/Ahab that awakens for the coma in hospital.
- The guide says that the fact that there are "The Star of Bethlehem" lilies in the Ishmael's and the version of Big Boss/Ahab that awakens for the coma's room is a strong clue to the real identity of Ishmael. The states that these were The Boss' were hold a significance to The Boss.
- When Ahab sees the ghost of Paz the first time at Mother Base, he has an hallucination where there are clearly two versions of Big Boss on the chopper.
