A faster Axis advance means most of the Soviet tank industry would be overrun rather than evacuated. This means that there wouldn't be that many of those pesky rattly-shooty-tanky thingies, in particular of the 30+ and 40+ tonners that axis tankers found so annoying.
I'm afraid there would be - for don't forget that by the time of the fighting around Moscow...anything up to 25% of Russian tanks - particularly the heavier ones - weren't of Russian construction anyway
