Is the graphic leap to 8th gen as noticeable as previous leaps?

[KBG29]

Killzone PS2

Killzone 2 PS3

Killzone 3 PS3

Killzone Shadow Fall PS4

IMO it looks like Killzone 1 to Killzone 3 is equal to Killzone 3 to Killzone Shadow Fall. That is late PS2 to late PS3 graphical improvment, looking the same as late PS3 to pre launch PS4. This should be where we expected PS4 to look 5 years in, and we have in pre day one. This will be the same case with 360 if the rumors are true. These games already look this good pre launch, pre final specs, and we have not see all the big dogs show their hand. We still have Crytek, Naughty Dog, 343, Santa Monica, Turn 10, Polyphony, Dice, and many more left to show what they are doing. 

One last thought. If it is true that devs were expecting 4GB, these PS4 games may even be low balling it. With devs seemingly having had access to 8GB + 32MB ESRAM  on the XB3 for a while now, we may see even more impressive things when MS unviels it in the coming months or weeks. 

Like I said in my last post, lets do this again after E3, and I'll also call for one post launch. I think many will have quite different opinions at that point in time.
