Some reports are stating that Internet Explorer 8 Beta will be included in Windows Vista Service Pack 1 (SP1) and be available by years end. No exact date is know for the release of SP1, so this is just a rough estimate. While many of the new features that will be included in IE8 are still unknown we had learned back in May that Microsoft is putting alot of focus on RSS, CSS and AJAX.
Although Internet Explorer 8 Beta could still be a long time off, it is also not that hard to believe that it will be available by years end. Given that the current betas for Firefox 3 and Safari 3 have both been made available to the public.
