This trailer right here expresses exactly why the jump from current gen to next gen is large enough

It's nowhere NEAR the jump that was N64 to Dreamcast or PS2 to PS3. 

tbh ps2 to ps3 jump wasnt much noticeable. launch title for ps3 were any much better than resident evil 4 and some other late gen ps2 games. i find this gen to next gen jumb much more noticeable.
