I think we will see a different Willie and Faf. The intensity is there and the concentration has been the highest order in preparation for the knock-outs. Plus it seems to me that some guys were given license to experiment, and Faf and Willie were certainly 2 guys that tried a lot of silly things, and a lot of it didn't work.
This is the team I think we all know that Rassie will pick going forward. Although, I think Nkosi has put his hand up to replace Mapimpi. But I wouldn't be surprized if Rassie goes for the 6/2 split on the bench again, and have and extra forward on the bench as cover.
The biggest difference between us and Scotland, is that our pack looks to dominate in every area, and not try and contain like the scots did. We will clear rucks, we will contend for the ball, we will try to win scrum penalties, we will maul and we will compete in the lineouts.
If Japan wants to have a chance against us, they will need to try and limit the amount of set pieces in the game.
