Is Microsoft profiting from X-box/X-box 360 at all?

I was just wandering if anyone had any figures on this or not.  Has the big M gotten out of the red yet on the the entire X-Box campaign.  They lose money on their consoles, and they spend a ton of marketing dollars.  Has it become profitable, or are they still loosing money on the whole thing.  Like the Halo 3 release, yeah, they will sell a Ton of Halo 3 games, but how many will they have to sell to break even on the game after dev and marketing costs.  Just thought I would get some ideas.
