Pachter may have a point, even though I suspect his numbers are (very) inflated.
In a way, The Order: 1886 reminds me of the original Uncharted. Both are new action-adventure/shooters with a focus on graphics and story made for a new PlayStation console. Like The Order, Uncharted was single-player only, could easily be beaten in under 10 hours (veterans can apparently rush through Uncharted in 3 hours), and did not necessarily have the most innovative gameplay.
As it turned out, the original Uncharted ended up selling nearly 5 million lifetime, despite being released at a bad point in the PS3's life. VGChartz data also suggests that this was not just a side effect of the sequel's success, seeing as the game sold best before Spring 2009, aka the PS3's tough era.
Assuming The Order is at least good at what it's trying to be, Sony can easily use it to sell the PS4 as a powerhouse, bundle it in multiple regions, and create a fanbase to guarantee a future for the franchise (along with keeping Ready at Dawn's interests close to Sony's). It can basically be the same cycle as Uncharted had last gen, but this time it could be even more successful because the PS4 is doing better than the PS3 did.
