Game-wise, in 2007 the PS3 received Uncharted, one year after the PS3 debut.
In 2015, the PS4 will receive Uncharted 4, about two years after the PS4 debut.
In 2008, the PS3 received MGS4, under the 2 year mark.
In 2015, the PS4 will received MGS5, around the two year mark (sooner if it's a summer release).
Infamous and Killzone made first year appearances on the PS4, as did LBP.
I suppose the only complaint, and it's not much of one, would be that some of the games that defined the Playstation brand in the 7th gen are the same ones defining the PS4 with some like LBP and MGS being available on last gen hardware.
If the discussion is in terms of original IPs, Infamous, Uncharted and LBP represented the early years of the PS3 whereas the PS4 really doesn't have anything that really defines it. The Order is really the only new 8th gen IP.
But as a platform tied to hardware specs, the PS4 still offers most of what the PS3 has now. The absence of external video playback off HDD, media remote, CD (nobody uses these anyway), and some of the lesser used PS3 functions are about it, which really just emphasizes more than anything that the PS4 is intended more as a dedicated gaming console, which is what the majority of Sony's customers wanted based on sales.
