Are graphics really going to be that much better next gen?

[oldschoolfool]

I'm just wondering are graphics really going to be that much better next gen. I'm sure they'll be somewhat better,but nothing mind blowing. I think this is going to be the smallest graphical leap we've had in some time. Don't get me wrong,I'm hoping to jump on the nextgen bandwagon at least a year after launch,but I want specific examples of how graphics are going to improve next gen. I'm not a tech guy,so if you give me examples,please dumb them down for the average consumer. I think some of these next gen games look somewhat better,but nothing that blows my mind. Please,help a simpleton understand all of this!!!!!
