Is now a good time to buy an Apple TV?

So what with Mavericks coming out and all I'm kind of interested in purchasing an Apple TV in order get in on that new "Extend Desktop" over AirPlay. It's not all that expensive either so turning one of my tv's into an external monitor doesn't sound too bad.

I know that some people expected Apple to at least update the Apple TV yesterday, but obviously that didn't happen. Do you guys think we'll see a new Apple TV before the end of the year or am I safe to buy one now?
