Ireland v Italy got over 100 replies too. There'll be a handful of dud threads for sure but I'd suggest the cleanest way to do it would be a thread for any game involving two tier 1 nations get their own thread and then a big one for any other matches which may or may not be discussed. E.g. Of the five games this weekend RSA v Arg; NZ v Aus; and Wal v England will definitely generate enough interest for their own thread, Scot v Fra is a bit more on the fence but with a return game next week the thread could facilitate both and certainly be ok and Ita v Rus probably belongs in a catch all thread for other games over the next month. I think its probably better to err on the side of a match needing its own thread because the discussion will be far more detailed and specific (and anal and pedantic...) than your average Super Rugby/Premiership/Pro14 regular season round.
