What I'm excited for is the "no compromises" part. Read any Digital Foundry article and you'll eventually come across something like, "it's clear that the developers decided to go with X at the expense of dropping Y." And that's just in the graphical evaluation. There is no telling how many levels had to be scaled back, how many enemies and NPCs had to be subtracted, or how much an AI had to be truncated just so they could fit everything in with passable performance.
It's going to be a big leap. I have no doubt of that. It just might not be a leap that you'll be blown away by when you compare two still shots side-by-side, but rather one that becomes apparent when you play a next gen game.
I think the biggest leap, however, will be with how quickly games load and how responsive gaming systems are. We're used to waiting a long time from system up to game start but early indications are that this will change for the better. I hope so, and think that this could be a huge incentive for people to jump to next gen.
