What the heck?
Update:
OK, by the time you read this, this is all over the blogosphere and probably the news. Since it seems to be such a new development, I looked on Technorati to see how long it's been discussed. The earliest mention of it I could find was this post. (Note that it's pointing to his web page at his hosting site, not at the walken2008.com domain.)
What's really cool is that what also came out recently — dated today, in fact — is the news that Walken wants to play a zombie.
Or, maybe it's the same story...
