I also predict the Xbox One version will outsell the Xbox 360 and PC version.

Xbox One version only. 500k-750k in its first week. 3 million this year, 1 million in 2015, 1 million in the rest of Xbox One's lifetime. Titanfall will have the sales of a Gears of War game I recon. Titanfall 2 will be an Xbox One exclusive and come in 2017. I'm calling it. Please comment and bookmark this please.

I am dead serious it won't.

It won't sell 3 million lifetime. Let alone this year.

And how much will it sell on the 80m userbase of the x360 and also the PC?

Whatever it sells on the xbone it will sell far more on the x360.

7m total sales on all platforms with good reviews I say.

Too early to say, for all we no the game could turn out horrible. But I wouldn't say 5m lifetime is out of the question.

How will titanfall sell more games than the system?

5m sales: possibly
Titanfall 2 exclusive: I highly doubt it

It will be the best selling version thats for sure.

Lifetime it could do any number, and IMO million is a pretty decent estimate. The game has tons of hype for it, and it all depends how good the reception will be.

If its a true AAA+ title (read 95%+ on meta), it could even do 7 million, 5 million in the US alone.

If its only good or, god forbid, mediocre, it could go as low as 3 million. But it will still sell good numbers

You seriously expect the Xbox One not to sell over 5 million lifetime?? is already 60% there in 6 weeks...

No it wont. COD 2 and 3 sold more on the 360, even tough it had far less units out in the wild then Xboxes. Gamers know that this is the first next-gen showcase for the X1 and they will embrace it as such.
