Different markets. Different expectations from consumers in terms of where their money is going.
Consoles have been around for a pretty long time now and people are used to spending $300-400 every 5 years or so on a console for video game entertainment.
Doing something every 2 years would put the Xbox brand in a similar position to Sega during the mid '90s -- many consoles, customer confusion, devs not knowing what to support, etc. Just wouldn't be that smart to do imo.
That's not an opinion, that's a fact. If they went that route, it would be tantamount to admitting they're no longer a gaming console. Unless every game from the prior iteration always worked on the newer one.
