True. But that means that the old AppleTV is now the only hardware that Apple is selling which has no software support. Pretty unusual, considering they're still supporting the 4S.
Not everyone wants what the new ATV is offering. I have no desire for games, more apps, siri, etc., and as such am not willing to pay > $99 for it. For how I use it, the (soon to be) old-gen ATV is perfect and now it'll cost even less!
