I'm thinking it's one way or the other. Either they're actually working on a 2.x upgrade for the current products, or they're about to discontinue support and release new products. As you rightly point out, they probably don't have the manpower to be doing both. I hope it's the former, but the dwindling supplies of the current models on Amazon (they're all almost out of stock), and the much larger profit incentive from selling new products makes me suspect it might be the latter. *fingers crossed*
