TUAW posts an unconfirmed agenda for the Apple event:
Let's just say I have been informed by a little reliable birdy about Tomorrow's event. The line-up will follow this similar structure:
Welcoming of Media Members
Discussion on iTunes software, iTMS integration into iTunes, and iTMS sales and facts.
Announcement of iTunes version 7.0
Announces better search feature for Music Store
Announces Movie Store. Available Immediately will be movies from Disney and Pixar, among other studios.
New iPod Nano Announcement (nice brushed casing, while it will have same features as first gen, only a longer battery life)
New iPod Announcement (Widescreen, Bluetooth, and featuring virtual touchweel. Does not include Wi-Fi, or any other protocols)
One More Thing....TubePort. A $99 2-piece set that includes a dongle that connects via USB to your mac, and another dongle that connects via included HD cables or regular Component cables to your TV. The movie is accessed on your Mac via an iDisk-like storage component hosted by Apple.
Jobs will then explain the pricing structure of the Movie Store. Movies will be available as either a smaller iPod-format (which will cost $9.99 per movie), or as a larger, streamed movie to be streamed to your TV via TubePort. This cost $14.99 per movie. To purchase an iPod-formatted movie and a streamed version of the same movie, it will cost you $19.99."
The same information was anonymously sent to this site as well as others.
When asked to clarify the "dongle" setup the reply was:
There are 2 wireless adapters in the TubePort set. One has a USB cable coming out of it that plugs into the computer, while the other wireless adapter has removable HD cables... these HD cables can be replaces with the included analog Component cables
....
Both adapters are wireless and communicate with each other. both adapters have LED lights to indicate status
The validity of this report is entirely unconfirmed and should be taken with as much authority as a anonymous forum post.
