But you have to keep in mind, although Sony has released in more countries, it has outsold in the places where both are released. Do I see the Xbox coming back with a vengeance when the next CoD releases? Yes. By that time the console will be out in most of the world, and people might actually have saved up their money to get their console of preference. I actually think Sony will stop pumping out consoles by the time the summer comes. Most people will have gotten a ps4 by that point, and the xbox will have time to play catch-up when it does hit more countries. So I see the sales numbers almost dead even with the ps4 slightly in the lead.
You do have a point though. Last year was a really bad year for software. However, I don't see CoD leaving anytime soon. The only game I see taking CoD's place is Destiny because it's on every platform (unlike TF). And even then, I won't believe it until some official word gets out. But since it's Activision, I assume they'll be out the day of release announcing the billions of dollars they made at the midnight launch (as is with all CoDs).
You're definitely right about TF though. I can only stand to play about 30 minutes before getting massively bored and going back to CoD.
