The new Master Collection includes a Master Book section with details about every MG realared product, mainline games, spin offs, comics and more.
The most interesting part is the new chronological timeline on it as the Book confirms both Revengeance and Portable Ops as canon and are included in the new official timeline.
I'm sure this is gonna piss off the most purist sector of the fandom a.k.a hardcore Kojima fanboys that think the man can do no wrong (lol).
I dont mind that as I found both Rising and PO better stories than PW and V, I hope Konami greenlights MGR2 someday.
Also, once again the new timeline never confirms Solid Snake death.
