Actually, even though Titanfall and Second Son are really close in numbers, Titalfall is actually doing exponentially better. If my calculations are correct, then those numbers suggest that approximately 65% of Xbone owners have pre-ordered Titanfall. Keep in mind I haven't actually looked up Xbone hardware sales; I've simply evaluated the conversations in these forums and quantified the majority opinion into an approximation of XBone's hardware sales.

generally, reservations increase the closer a game is to release.

4 million across all platforms?  maybe.  on xbone?  no. 

online multiplayer games needs an active community to play against or it isn't fun.   titanfall will launch when xbox is less than 5M consoles sold so the most it could hope for at launch is ~2M; a very repectable attach rate.  a far greater attach rate than i believe possible when guys like me (who won't buy an online only game) simply won't buy it.  single player isn't th filler to me,.. multiplayer is the filler which on most games i don't touch.    ...and as nearly all online game's communities go bust within a month or two of launch i absolutely believe titanfall's community will too fail soon after launch.   ..and with it so does titanfalls sales legs.    

i said disappoint.  i mean disappoint.

I think your reasoning is very flawed.  It is surprising that Second Son is not substantially ahead of Titanfall - given it has two existing games with solid sales, and an equivelant marketing push from Sony.

5 million copies sold for Titanfall (assuming it releases by April next year) would require every single X1 owner to purchase the game - and attach rate of 100% based on the number of consoles it will launch too.

I will allow for the possibility you just didn't quite grasp the history of these two titles, and the context of the market they'll launch into, but its hard not to feel like you're deliberately trolling...

I still don't see how titanfall can be a systems seller when it's available on PC and 360. 360 will get most of it's sales it's probably going to cut the legs out of the xbox one version simply because many people cant spring the 500 and people will want to play with their friends likely making many xbox one owners spring for the 360 version just to play with their clan mates. It will still do well on xbox one, but it's likely the online community is going to dry up pretty fast. Example.. 800,000 copies of ghost sold on ps4, and only 20,000 people online at any given time. Some game modes are impossible to get a game in, having as little as 200 people in the lobbies.

But i think infamous is going to do pretty well. Maybe 3 million after a year on the market. Depending on how well the PS4 continues to sell.

I'm more surprised on FFx/X-2's numbers! It's probably gonna be the best selling HD remaster of all time! Although I do hope we see the vita versions soon. If only Squeenix would announce something about the vita versions.

They will understand that was a mistake to not release it on PS4

Titanfall on xbox one is gonna kill infamous in sales in my opinion. It is a bit disappointing that it's multiplayer only, but most people who play call of duty and battlefield play it for the multiplayer first.

Iam geting infamous ss on launch day

doesnt this actually mean titanfall is better? its beating a known ip on a console with more people
