He isn't saying anything wrong... but also anything surprising nor greatly worrying.
All the trailers are smoke and mirrors.
If you look at the trailer and videos released in spring and E3, it seems a super polished product, a finished game!! How is that possible, if they have delayed it until 2015? What are they doing in 10 months of development?
Of course, the answer is that trailers are done to make it appear as good as possible, even if the real game is still buggy, animations are still half done, optimization work is still barely started, etc.
But, that's every game, ever. Therefore, if that happens with every game, including games that finally result in a good game, and games that finally result in a bad game, it can't be said it's evidence that points to being finally a bad game.
Of course the PR doesn't mention the bad points, doh.
And of course their final interest isn't in the consumers, it's in the money, the profits. That's a business for you.
Oh noes in truth they are in super crunch mode finishing the game... lol. That's how every ambitious game is made, and even most of the non-ambitious ones. That's the (sad) truth about game development.
Edit:The part that can be valid is how the console versions are going, who knows if they are less than stellar and most of what we saw was the pc version.
