Microsoft is experimenting with a new pricing model for its Xbox 360 console, namely $99 human dollars up front, tied to a $15 per month subscription to Xbox LIVE. The idea is to pass the full cost of the console on to the service, paid a little at a time. It’s a successful model, used in the cellphone world, among other places. The real question is, what if this experiment is a model for the upcoming next-gen Xbox? IGN has the story.
