Well I never Pre-order games, due to the fact that you're not actually buying a game, you're buying hype.
Frankly if you Pre-order a Game you lose the right to complain the games crap when it's released.
So to those who cancel now due to last minute cold feet, I've got to ask why the hell did you pre-order any game, even this one, at all.
Also noticed they were all Steam buyers as well, so a word of advice for those Steam Cancelations. When you realise this game is awsome, get it on GOG instead as penance, not for cancelling, but for pre-ordering at all, from Steam, the worst places to get any game sold on GOG.
Now Having said I never pre-order, I actually sort of broke that rule for the Witcher 3, but I did so to support GOG, if the game ended up being unexpectedly rubbish, it didn't matter to me. GOG was always getting my money for it.
I didn't buy any of the Hype to start with, The game is Awsome, acclaimed by all reviews so far and no PC reviews are out, not I think for any other reason than CDPR want reviews of the finished game.
I'll judge it myself, solely on what's installed on my PC and nothing else matters.
