Steve doesn't really play live drums. On the last tour he was playing roland v-drums (except for a triggered yamaha kick). Obviously this simulates acoustic, but lets be honest, as far as I know he has always tried to be a human drum machine (he's no Keith Moon). To suggest that his lack of playing "live" drums is a significant change from 80's era new order is ridiculous. Almost every single they've had features programmed drums, and I don't think he's actually played an acoustic (i.e. non-electronic) kit since about 1985. As far as I can tell, roughly half of Low Life is programmed.
As far as WFTSC, it sounds to my ears like he's playing his v-drums on about 50% of the tunes. And he personally took credit for coming up with the riff for "Working Overtime".
If you pay attention to Steve's style, the greatest change occurred between JD/Movement and PCL. He virtually stopped playing toms. What's cool on WTSC is that he actually remembered he has a ride cymbal to use, which I don't believe I've heard since Unknown Pleasures.
In other words, this whole debate seems pretty silly. Musicians change, and each New Order album is wonderfully unique, reflecting the time and era in which it was written.
