pretty good, but important to bear in mind that the UK is always a good market for Microsoft/Xbox and that it's not a GIANT market. This is sort of similar to announcing that the Nintendo Switch had a great opening weekend in Japan when it launched.... it's sort of a gurantee
I'm more curious what total numbers will be as I think the tougher battle was going to be to convince the North American market and rest of Europe to be okay with buying a $500 console. Too bad Microsoft never releases overall numbers for this sort of stuff
