Microsoft Officially Announces $99 Xbox Deal
Microsoft is going to start selling Xbox 360s for $99. Two catches: you can only do this from a Microsoft store; and you have to agree to pay for two years of Xbox live at $14.99 per month.
The normal per-month XBox Live subscription price point is $9.99 and it doesn’t look like you’ll be able to opt for paying for a yearly subscription. With this deal, the total you’d pay for the Xbox over two years’ time is about $40 more than just buying the Xbox and two years of Xbox Live.
In short, they’re setting up Xbox loans using their preexisting infrastructure. I must admit, I’m curious about whether or not this allows them to circumvent banking laws regarding loans and, if so, what that does for the company.

I personally think this is Microsoft’s pilot project for a much bigger move next-gen. Imagine being able to sell the next Xbox for something like $200 at launch, under a three year contract for say $20 a month. This makes the system appear cheaper for those that are going to want Live anyways.
I’m quite curious to see how this all pans out. Cellular companies have been doing this for years with their smartphones and have had tremendous success, but are people willing to do the same sort of thing with consoles?
