That is true Super-San. However, this was Sledgehammers first attempt at bat. Despite the criticisms they have taken, they did a commendable job in my opinion and do not entirely deserve the flak they have been taken regarding how the game turned out.

Treyarch, on the other hand, does have a basis to build on in Black Ops 2. Three years definitely have helped as the game looks good so far to me; sans weapon balancing issues. However, thanks to a beta week, most of these issues will be ironed out. Furthermore, Black Ops 2 was the best Call of Duty the series has had. While itnwas no doubt the peak in terms of sales, the game was arguably the most balanced game since Modern Warfare. I am sure David Vonnderhaar will not let three years go to waste. If he made Black Ops 2 a success, then there is reason to believe the extra year will affect the game tremendously.

XB1 version will be competing with Halo 5 so PS4 by a substantial margin.

No, because those people choose their consoles based on which consoles their friends have. They're not just going to switch and leave their buddies behind. And no, no one can convince me some timed DLC is going to convince like, 7 friends to sell their consoles on Ebay lol
