AppleTV Take 2 question

Ok, so per the Macworld announcement yesterday, Apple TV is getting an update called "Take 2." I THINK it's a software based thing, so any current Apple TV units can be upgraded, right? Is there ANY other physical difference in the new boxes compared to the current ones? Also, if I buy an Apple TV today, can I stream movie rentals from iTunes to the Apple TV? Or will that not work yet?

The thing is, I called my local Apple store, and they couldn't even answer my questions. I thought that was pretty absurd.

It's a software update...Rolled out in 2 weeks..

Can the current AppleTV software view iTunes movie rentals from a Mac?

No, you must wait for the Apple TV software update in order to stream/sync movie RENTALS to it.

SO it is the same machine only software so there is no need to wait for the release of take 2 correct?

correct. i just got an ATV so im just not so patiently waiting for the update haha
