I'd have to say you're a fool if you only see "minimal graphical differences" when it comes to the exclusives. The best graphical game for the 360 is Gears 2. Plain and simple. If there's anything in development (most of which we know about), they don't surpass Gears. On the PS3 side, there's Heavy Rain (that's the big one) Uncharted 2, and if David Jaffe is anything to go by, GoW3. Plus, inFamous is using a deferred rendering engine like KZ2, so depending on design, it could look better than KZ2 also.
And all of those games graphics > Gears 2
And before you say "How do you know, you haven't played them, they're not out yet"

GoW3.....just look at the latest Game Informer
inFamous is the only one I'll concede as MAYBE not being that great looking....but then again, it's using the same rendering engine as KZ2....
