Internet Explorer 9 is coming. The number 9 is a guess, but Microsoft is not getting left behind in the web browser scene again. With Internet Explorer 8 being released 5 months ago in March 2009, we have little information so far as to what is going to be included in the next release. We knew two things Microsoft is doing, they are asking customers for feedback, and they are investigating HTML 5 features.
The second thing we know is that Microsoft has been reading the HTML 5 spec and recently posted feedback on the public W3 mailing list. This indicates they are interested in building HTML 5 features into their next web browser; although, at this point its anybodies guess as to what they would implement. We await more information.
Estimated Release Date: 2012?
