Beyoncé tour can easily benefit on South American and Asian dates if Bey plays her cards right. Beyoncé will be also ahead of Rihanna in North America easily.
Now the real question is if Rihanna peaked in UK or not. Let's not forget that HUGE chunk of her Loud tour gross came straight from the Islands. I mean from overall $90M, over quarter came from England/Ireland/Scotland. Actually counting only London, Manchester, Dublin and Belfast dates we get $20M+.
Oh and let's not forget that Rihann landed in hospital couple of times during Loud Tour, that's for people saying she can always add more dates
