England currently lead pool B with 14 points from 3 games. Argentina and Scotland both have 10 points from 3 games with Argentina set to take on Georgia.
Only two teams can qualify from the group so there's everything to play for.
It harks back to Murrayfield in October 1991 when Scotland entertained England in the semi final. England travelled north who having emerged triumphant in a bruising quarter final encounter.
Scotland had, of course, derailed England's Grand Slam hopes in 1990 and had every chance of thwarting the 'Auld Enemy' once more.
However, England squeaked it by 9 points to 6 in a game which will be most remembered for Gavin Hasting missing an absolute sitter of a penalty from in front of the posts.
Saturday's game has obvious interest for Gloucester Rugby followers. Mike Tindall is a regular in the England midfield and it would be a major surprise if he's not selected.
It's less straightforward predicting which Gloucester players will represent Scotland. Jim Hamilton, Rory Lawson and Alasdair Strokosch all started against Argentina last Sunday while Scott Lawson has had a calf strain.
Scotland haven't really hit their straps so far beating Romania 34-24, Georgia 15-6 while losing 13-12 to Argentina. Head Coach Andy Robinson's team selection could be fascinating.
There could well be a lot of TV sets in the county tuned in to the game on Saturday morning!
