That's how console market works since... forever. Maybe with few exceptions like recent Nintendo consoles, but the general rule is always the same - you want to push as many consoles on the market so that later on you can sell more software. The elephant in the room here tho is that not many people would be willing to spend 800, 1000, 1200$ on an XB/PS console, whereas hundreds of millions gladly do so on an iPhone/MacBook/iMac etc, and no one can blame Apple for that.
