I am currently downloading it. The links went live just a few minutes ago.

Update: the Developer Tools are still very young and unpolished ; but having finally a JS debugger and a HTML+CSS inspector in IE is cool. Other than that, IE8 does not do a better job on my selectors test than IE7 did. I still HATE having the addressbar above the menubar. The "Emulate IE7" button seems to me a terrible danger to average users. They will NEVER understand what it means and why it's there. I'll test IE8 in greater details later and I'll post the results here on my blog.
