Sure we do, any game that has digital version is undertracked.

they do on occasion give that, ala Gt5p being over 1m under on here compared to official number. 

thats not undertracking it, thats simply not tracking the Digital Version since they cant. VGC tracks Retail and not digital. 

the only things we know is that UC3 week one sold double UC2 week one, and that the series as a whole sold 17.32 million as of April 2012 (that includes UC:GA on vita). VGC has it at 18.5 million now, while we do know that the franchise i most likely undertracked since Uncharted 3 alone sold around 2 million in the past 2 years (according to VGC) we cant really dertimine if UC3 is really undertracked or not. we are simply making an educated guess. 

Yep things dont grow dont ever improve.  Games never out sale its predecessors. 

Except for the unrealistic hype Sony fans have build upon this game on this website there is absolutely nothing and I repeat NOTHING to assume this game is going to sell more than double than its predecessors. Even Killzone is a bigger franchise than inFamous but it didn't even managed to sell 2 million despite it being a launch game. Max 2 million for this game. 4-7 million isn't even funny in Imaginationland.

3-4 milion. :)

I picked 4-5 mil. 6-7 mil would shock the shit out of me. Yes pun intended lol

You part right, there is nothing and i mean NOTHING to play in the forseable future but Infamous.  Thats the common sense reason why its gonna sale way above what it normally would, just like TF is gonna sale on X1 as there is fuck all else to play this will go above and beyond common sense as to what it should sale given normal circumstances.

And hype is real as its a hell of a good looking game one of the first true new gen titles not some update texture bs, full on PS4 game.  Its from a quality developer it will get heavly pushed by Sony its on the domminant selling console.  It has everything going for it to sale way above expectations. 

Actually KSF sold over 2.1 million, as of a month ago.  And it had COD and BF to compete with, but im sure that didnt hinder sales at all. 

Only thing that could hold it back is if it gets bad reviews.

Even with 2,1 million for Shadowfall, my point remains. Killzone is a much bigger franchise with about the same units sold per installment (2-3 million). inFamous 1 apparently wasn't good enough for inFamous 2 to sell more or equal (but about 50% less). How are you guys ever assuming this game is going to sell between 4-7 million? It doesn't make any sense. Just think logically for one second, please.

3-4 millions I said

- First real next-gen game
- Reboot of a franchise and this is why, it's Second Son and not inFamous 3 to attract more people
- According to people, the game is a great improvement from the first 2 so great reviews incoming = good buzz
- Not a lot of games on next-gen, so this one looks gorgeous + good reviews = good buzz
- The game takes advantage of the hype PS4

inFamous 1 did 270k first week
inFamous 2 did 320 first week

I think, the game can reach at least 500-600k first week
