Major warning for all. Miller will be begin his Let's Play series of MGS5 the SAME DAY that review embargo ends. You all have been warned.
In addition, many sources are stating that there will be NO PRELOAD for the Steam version of the game. So that's fun.
In slightly better news, almost all of the people at the bootcamp right now are saying the game is amazing, with many citing an 8 hour play time and only 5-6% completion rates. Edit: Many are also mentioning that there are many twists and turns have already happened in those initial hours, so probably worth avoiding the Greg Miller stuff if you can. These are the final days people.
Two major edits, sorry, things were a bit unclear initially about this, my fault. This is why you shouldn't post right before you go to uni.
Edit 1: Though there is no official pre-load, apparently everyone who pre-ordered the game will be able to download and play right when the release date for New Zealand rolls around. Which is pretty damn early.
Edit 2: Greg Miller will NOT be going through the hospital sequence. and will go ONLY up to the 5th Story Mission.
Incredibly sorry for the confusion.
