Halo 5 retails for 40 pounds, so that works out to around 190k.

How does that compare to Halo 3?

I think it would be ideal to add the "In the UK" but to avoid misunderstanding, but yeah, Halo 5 is certainly gonna earn Microsoft $$$

All we know for now is that it sold higher than MCC but lower than any other mainline entry in the series in UK

Can't really count it that way because there's also the limited edition and the collector's edition which increase the average price but by an unknown factor.

About 150k

Don't forget the limited editions that retail for higher. I wonder how much of that £7.7M is profit for MS

But that's for 5 days of sales, sans digital sales.

GAME sell it for £45. Don't forget there are also the Limited Editions ranging from £70 to £250. So probably want to lower the sales tally slightly. Maybe 170,000? Which would be about right with the figure in the other thread when you include digital sales?

Halo 3 sold 370,000 in the UK week 1 according to Gaf with Halo 5 listed at 150,000 for week 1 (not including digital).

170k including digital sounds about right

Is that after costs for advertising, shipping, distrubution, packaging, devolopers. What is this mysterious 7.7 million you speak off?
