Xbox 360 with built-in HD-DVD drive being announced next week?

So there's this rumor on Australian site Smarthouse (via Kotaku) that Microsoft is working with Toshiba on a 360 with a built-in HD-DVD drive.

The machine would also include television tuners (so you could use it like a TiVo) and docking ports for MP3 players.

The site says the new configuration wouldn't be available until the end of 2008 at the earliest.

BUT... I got a call from Microsoft today asking to set up an interview next week to discuss an Xbox announcement. I'm out of town on vacation next week, so I can't do the interview and they wouldn't just go ahead and tell me what the announcement is, but Microsoft doesn't call me often to discuss new product announcements.

Now, this announcement could be about anything (Microsoft has repurchased Bungie! Nintendo has purchased Microsoft! Google has purchased Nintendo!), but it's curious timing.

So next week could be interesting.
