I think there has been an improvement in that direction already. at least to my ears (I use a lot of external drive pedals as well). it happened around the time when the guitar volume knob/amp interaction improved as well. things got far more dynamic. so I don't think it's 100% a/d conversion related.the thing is that using an axe od into a real amp yields better dynamic response than going with a real pedal into the axe amp, that's why I think the limit is not within the drive block, but it's in the interaction between distorted signal going into the axe amp sim. For example, if I try a ts9 or a sd1 into a real amp they sound much different than if I run them into the axe amp, same thing if I run the axe ts808 or super od into a real amp, if that makes any sense. And just to be clear, I'm not saying this is an issue, I'm just saying that would be the last improvement I could think of!
I've done tests with my old TS10 against the Axe's TS and the results were very similar when running a real vs. the modeled OD in front of an Amp sim. one thing that may react differently to a real amp is when using an OD mostly as a boost on high settings. some real amps may have a different headroom and therefor just react slightly different. but simply using pedals for dirt, the gap is very small...
