We're excited to announce that development for the new (black) AppleTV is underway! Things were able to get going a bit earlier than expected as the software for the new AppleTVs was released before the devices actually shipped.
Most who pre-ordered, including us, received they're AppleTV shipments yesterday. The long and short is the new AppleTVs have an A4 processor, 8GB of storage, 256MB of RAM, and built-in Bluetooth. There's even been some encouraging discoveries that may allow for full 1080p playback on the new models. iFixit has a very comprehensive teardown article that outlines many hardware features, and includes many hi-res photos - the article can be seen here.
