Xbox 360 Controller Keyboard?

I was on Gamespot.com earlier and noticed a post about a keyboard add-on for the Xbox 360 controller. When I clicked the link to read the post, the link broke. Is the another case of Gamespot running a story and retracting it, as they did with the Spring 2007 Dashboard Update? It seems so, since the link is no longer on Gamespot.

So, I think the controller add-on looks great, though I would really like to know more information. Anyone have any links to some hot juicy rumors? Oh, and just so you know I am not going crazy and seeing things that are not there, check out a screen capture from Gamespot ;)

UPDATE** Engadget.com has an article up too, with a great picture (posted below). They posted the attachment will be released sometime this summer.





UPDATE** Major Nelson spilled the official beans on the keyboard and the Spring dashboard update. Both are formally announced.

UPDATE ***7/12/07 Microsoft has announced the keypad will be available September 4, 2007, check it out in Microsoft's Xbox Hardware Catalog.
