Just how high is that High Definition?

So you're pumped up at the idea of iTunes HD rentals? You want to grab iTunes 7.6 and get the crystal-clear movie-rental goodness? Not so fast: what exactly IS the resolution of these forthcoming High-Definition rentals? Where on earth can you find out just what resolution the movies will be in?

Thankfully, you needn't look farther than our brethren over at Engadget, for they point out that as the AppleTV has not been updated on the hardware front, we can still expect the maximum playable content to be 1280 x 720 pixels. That's not to say that there will be movies at 1280 x 720 resolution, but if you're hoping for 1080p content to arrive on your freshly, and freely updated Apple TV that might not be the case.
