Hey, IE 8 Coming Soon 2008! Anyway, the date of releasing IE 8 has not been announced yet, but microsoft promised that it will be released in 2008.
Currently, Microsoft is soliciting testers for its IE 8 beta 2.

Beta 2 is right around the corner and we are expanding our reach! If you wish to be a part of making IE better by contributing great bug reports then please email us at IESO@microsoft.com and tell us a little about yourself including why you’d be a great beta tester.

Will you be one of them?
