Some major retailers seem to be selling the Apple TV 2 at a discount, leading 9to5Mac and TechCrunch to speculate a new model may be incoming and soon.
It's also being tagged as the 2010 Apple TV, leading to further speculation a 2011 model is nigh, though I think the Apple TV 2 has been referred to as Apple TV (2010) almost from launch to differentiate it from the original, non-iOS model.
