(Up to 5 days of early play) emphasizing the word "UP TO" That is lawyer's term for "no guarantee".
Pre-ordering the game does not guarantee you 5 days of early access, just like buying a new Corvette does not guarantee you to be a better driver. This means you can't blame Chevy because you suck at driving.
Bioware does guarantee you access on the 20th.
I dislike it as much as anyone else, that that's life. People have waited years for this game, a few more days will not kill you.
