jul 1, 2030 - Side note anything that is strictly not canon is left out, so unconfirmed is more up to the imagination, personally I'd say Ghost Babel is Raiden training in simulations and Mobile is Snake discovering the simulations. Portable Ops is referenced in MGSV and Peace Walker so i don't have any problems with considering it canon, and Revengeance (as awesome as it is) just doesn't suit the canon in my opinion, MGS4 is the perfect ending to the series chronoloically speaking.
