Wow, I think it might be able to sell the 400k first week. Which is amazing for a new IP, and it's coming out in March, which thing usually don't do that well and it's on a brand new console.
Then the big question will be how good it's legs are. If reviews and consumer enjoyment is high, I could see it doing very well for a long time. Especially if it's another 2 years for TitanFall two.
PS the controller is so nice, wish they made that console too.
