I did not say there wouldn't be any tradeoffs, I just found the reasoning used by NovemberMike to be somewhat off the mark. I believe the new HD consoles could produce Crysis to a degree where the end result could be viewed to be better than just "looking like shit with tons of loading screens"
Yeah, I can agree with that. Crysis is all about next-gen physics, animation and of course visuals. It's my (perhaps biased) opinion that they wouldn't drag their 2nd Generation engine into the proverbial dirt by allowing it to look "bad" on a console.
Besides PC-games are not developed only for the higher end, there aren't that many systems with 4GB or more ram... The fact that the game has to run acceptable on mid range machines too puts restraints on the game development and then most of what you're really getting from your monster machine is higher res and AA which is nice, but for many of us not that big of a difference, once you get beyond certain point. Naturally small differences can be lifted to a pedestal if it suits the need of the argument.
Quite a few games fit what you just described, but I do not believe Crysis (and for proof of this, look at FarCry) fits into that same mold. When you have view distances on the order of
kilometers and single-frame scene complexity into the
tens of millions of triangles, then you have a LOT of wiggle room between a "low-end" PC and a "high-end" PC.
Look at what you were able to do on FarCry - you could playable framerates on a Ti4200 even at 1600x1200 resolutions. Now granted, you didn't get reflective water, the object density goes to nothing, judicous amounts of terrain LOD, sprites replaced 3D models at about 100 yards out in view-distance, fish and wildlife went missing and some other items -- but it was 100% playable and actually still looked quite good. And we aren't even talking about AA and AF... (I can provide samples if you like)
Now again with FarCry, you could even drag an x800xtpe (brand-new, top-end at the time) into the dirt with the game at full capacity -- full water reflection
and refraction, object density at 100%, all 3D models and no sprites, zero terrain LOD, flocking birds and schooling fish and fully dynamic shadows. And again, we aren't even talking about AA and AF yet. (I can provide samples of this too)
Looking at Crytek's past engine history, I'm VERY certain that the engine underpinning Crysis is fully capable of dragging a full-bore gaming machine into the framerate-dirt without turning on AA and AF. But at the same time, I'm quite sure it's capable of looking fantastic even on "antiquated" hardware.
