I think it will be a system seller but not a big one.

I used to think it was all about the system, but then I realized that the system is no fun if there aren't games.

That's okay, you're entitled to your opinion.

I'm a gamer so I love games, in order to play them it helps to have as many consoles as possible though for the different games and experiences I can have with that, so that's how it works for me. I have like 4 consoles + PC to game on right now and that's pretty good for me, heck I have more gaming I can do on my iPad or iPhone as well

fanboys just seem odd to me, you're a gamer, enjoy gaming, don't worry about PS this or XBOX that or Nintendo this or PC that y'know, just game and enjoy it, whatever platform(s) you got's

a system seller I guess is any big name game that get's a lot of attention but is single platform or at least timed exclusively or has exclusive content/features, so something like Gran Turismo is a big system seller for Sony as it's PS3 only and has brand recongition, Halo does that for the XBOX 360 and for Nintendo most of their games have the brand recognition as well,.

That would mean 1/2.5 xbox one buyer is interested in Titanfall week one. That's more than GTA 5 on PS3(10m GTA5/ 80m PS3).

Titanfall is not a launch game for the Xbox One, but is estimated to release in Q1 2014.

If you had read the other comments in the thread, you would have seen that already discussed.  I didn't say it was a launch game for XB1, I said it will sell 3 million in it's first week and also boost XB1 sales by 200K that week.

Then why did you refer to the game launching? Most commonly people refer to games releasing and consoles launching so when you said "I think it will sell 3 million games at luanch" (misspelled launch by the way) I presumed you meant the console.
