Microsoft has made at the very least around five to six billion dollars in net profit off of the XBOX brand. You can't get that out of the financial statements however. The division that houses XBOX is filled with many product lines, and probably a great deal of non gaming related R&D. The best you can really do is some common sense math. Plug in the variables, and even if you are very conservative you get some staggering results.
A few years ago this community did that math, and reached the consensus that Microsoft had already turned the corner on the brand. Factor in a profit as little as twenty five dollar annually per console sold, and you reach a net profit of at least five billion dollars. Which isn't only conservative, but pretty damn hard not to meet on the part of Microsoft. Given all the revenue streams the company utilizes. You can break that up however you like between royalties, subscriptions, advertizing, and retail profit.
Now if that argument doesn't sway you then this should. Does anyone seriously expect Microsoft which is a very competent company to make less then a dime on every retail dollar. They don't even have to make that dime all at once. They can make it over the coarse of years, but it is hard to see them never reaching that dime. They just have too many ways to get that money. Even if it isn't all at the checkout the subscription service alone could cover the shortfall.
