No way, not even with Uncharted 3/ LittleBigPlanet/ Resistance: Fall of Man level of mass bundling. Out of all of Sony's IP's only God of War and Gran Turismo can reach 5m+ in a short period of time (less than 2 years) without mass bundling, Uncharted 2 was bundled more than GoW3 & GT5 combined and sold a majority of units at bargain bin prices so I don't consider that at all impressive. And yes, God of War III has sold over 5.20 million to date but Vgchartz lacks the effort to fix the numbers after mistakenly resetting its numbers back to pre-adjusted figures. It can't possibly be that difficult to change a number that's been proven wrong can it?! The entire franchise was massively under-tracked and all the games were adjusted but God of War III was reset the following week, I bet God of War: Ascension will be massively under-tracked too.
Anyway, for PS:ASBR I'd guess that without bundling (highly unlikely) it'll sell 1.5-2.0 million and with mass bundling 3.0-4.0 million.
