Injuries have come thick and fast for Warren Gatland's squad already but their depth is evident and the head coach has called on a strong XV.
That features four Ospreys, three Cardiff Blues, two Newport Gwent Dragons and scrum-half Gareth Davies, the sole representative of the Scarlets.
Scotland also boast two wins from two - with a maximum points tally of ten to boot - and put their perfect record to the test against South Africa on Saturday.
Across victories over Japan and USA, nine different Scottish try-scorers have pitched in, Glasgow Warriors centre Mark Bennett leading the way with two.
His GUINNESS PRO12 teammate Stuart Hogg was named man-of-the-match against USA, while fellow Warriors Tommy Seymour, Finn Russell and Duncan Weir - as well as Edinburgh duo WP Nel and Matt Scott - have each crossed the whitewash.
Ireland, too, are on the hunt for a third triumph in as many games when they meet Italy at the Olympic Stadium on Sunday.
Munster man Keith Earls grabbed a try double in their 44-10 victory over Romania last weekend, taking him level with Leinster legend Brian O'Driscoll as Ireland's all-time leading Rugby World Cup try-scorer.
Leinster full-back Rob Kearney, who has scored in each of their matches, is on track to take part - despite picking up a hip injury - while his provincial teammate Jonathan Sexton should re-take the reins at fly-half.
Italy, meanwhile, collected their first win of the World Cup on Saturday when Zebre centre Gonzalo Garcia crossed over to help them to a 23-18 over Canada.
Scarlets new boy DTH van der Merwe grabbed his second try in as many games - and an eye-catching one at that - against Italy and will be hoping to carry on that form when they meet France on Thursday.
And Cardiff Blues centre Rey Lee-Lo could line up for Samoa and Japan on Saturday, while Edinburgh wing Will Helu will be hoping to take on Argentina the following afternoon.
