They had "Kindle Editions'" listed yesterday but pulled them today.
They'll surely be back once the Kindle has become official news...^^
I'm not sure why the "Kindle Edition" titles were there yesterday, but I guess it was either a mistake (unlikely) or a "probe" to see whehter people notice and how they react.
The links were dead yesterday, but that's to be expected since you are supposed to get these titles delivered to your Kindle via wireless and since there is no Kindle yet...
