I could really use one now. I'd buy one of the existing ones, but man... I really feel like a sucker paying so much for a system that's clearly lacking in a lot of spots, to know that I'll be upgrading in a year.

Buying electronics is always a gamble of buy now or buy later. Announcing there is an update coming can poach some sales of the current model. I'm sure there is more to it than that. but it can happen.
