According to the IEBlog at MSDN:
….we’ve been working on great new features for consumers and IT
professionals (as well as doing even more cool stuff for developers). I’m happy to announce that we’re on track to deliver IE8 Beta 2 this August when you’ll get a chance to see what we’ve been up to in these areas. Furthermore, in order to help us get even more feedback for this global product, we’ll be releasing Beta 2 in over twenty languages within a month of the initial release. This is a big step up from the three languages we released for beta 1 and much more than we ever did during IE7.
Personally, I wasn’t all that impressed with Beta 1 of IE8, and I am concerned that Microsoft has lost some ground to the excellent Firefox v3. However, I do look forward to Beta 2, and I do not recommend anyone install beta software on a PC without knowing the risks involved first. Beta software is ‘buggy’ meaning that it is a work in progress, and there are a lot of issues to be resolved before it can declared stable enough to be released publicly for everyone to use.
