Doesn't seems like it, a 5M+ FW seller would need a ridiculous amount of hype.
As much as Uncharted has a good hype, and the PS4 is way better than the PS3 to be able to reach more gamers, this will simply not happen. The only thing I can think would be able to sell as much and so fast would be a new TLOU, if it's able to keep up for the first game and actually surpass it.
Uncharted 4 will sell very well, but I doubt the franchise has such levels of hype behind of it.
And don't forget it's coming on a slow period of the year. It may have huge legs leading to the holidays, butthis numbers seems just too much, really too much.
