Wow, late to this party! These are interesting statistics, but Launch is when? May?
Remember Crestwood and the closed demo, spectacular gameplay -DAI never got it.
Crysis 3 had significant numbers of buildings, but only a few had any function, the grass and trees moving in the wind had more function.
ESO had plenty of NPC wandering around and most were about as interesting as the mice and birds. Point being, intelligent dialog and behaviors to make interesting characters is demanding on the front end and on the user end.
Similarly, witcher 3 will need to be scaled back when all platforms are tested -it's hardly all set in stone yet and it could slide again. Hope that they have good QA with the balls to stall launch if/when the errors pop up.
There is also the management side: Bioware/EA stumbled with technological development, they did not fall and there is plenty of creativity and significant game development investment as well as QA -I know thats hard to bite, but it's in black and white. Bioware and EA also know that this stumble was costly to their image and that their IP (intellectual property) is at risk...I would not count them out so easily.
