oh c'mon. Sure it's not as big as 2D to 3D, but your comparisons mostly suck.
We've seen FFXV footage. Why don't you include that in your FF comparison (or FFXIII footage for that matter) ?
Forza Horizon to Forza 5 is a bad one. They are coming out within 12 months of each other. Also Horizon was only half the FPS. Why not doing a Forza 1, Forza 3 and Forza 5 comparison ?

MGS4 to MGS5 is a huge step IMO
