It's hard to say without actual figures, but I'd be surprised if Killzone:Sf has outsold KZ2 (the franchise high mark) or if Infamous:SS has outsold Infamous 1 (the franchise highmark).
Both titles hugely benefitted from launch drought 'must buy something to justify my new toy' as well.
EDIT:
Which franchise titles selling more on PS4 than on PS3 are you referring to here?
All of the "definitive edition" ports sold less than their respective last-gen cousins entirely because of userbase discrepancy.
Both Shadow Fall & Second Son were the fastest selling in their respective franchises, we don't know if they sold better overall or not, but the small userbase did not prevent SS from selling 1 million in 9 days, which was the fastest the franchise has hit 1 million, & Shadow Fall sold 2.1 million in less than a month & a half.
