Unless some miracle and video game data doesn't matter, Titanfall should not have as big of an impact such as saving the xbox one and beating the ps4. Lets face the facts that youtube titanfall has only 2 million views on its largest video. We can't really say that a game is going to sell 20 million when only like 3 million people on the planet earth knows this game exists. There are other problems that need to be stated. The google search trend numbers and twitter numbers. Twitter there are only 12,000 tweets for this game. That isn't that large and shows that they need to do something to increase awareness of this game. It is after all coming out in 2 months. Another problem I have is if you look at the last of us and titanfall you would notice that it appears to be trending on googlee in a similar manner. It really has zero chance of selling call of duty numbers. I expect it to sell around 6-8 million with around 2-3 million on xbox one at best. A system seller it isn't. But keep on fighting the good fight. I like seeing irrational crazy fanboyism hype with no data backing it up.
Here is a summary of what I am saying:
Preorder numbers aren't that high
Awareness of the game isn't that high
Twitter and google trends aren't that high
What it needs is a huge marketing campaign and high reviews to sell around where I think it will but that is my opinion.
