The Internet Explorer 6 update to Windows Mobile is the only anticipated update to Windows Mobile coming over the next few months. This update itself has been expected by now, and itself appears delayed.
TheUnwired however now has some proof that the update does actually exist and appears to be coming close to release. The screenshots, visible at theunwired.net, shows the browser rendering the website both in mobile and desktop mode and the method of switching the mode. Unfortunately the browser does not seem to have caught any of the style from its main competitor, Opera Mobile, and still features prominent scroll bars and seems to be only single tabbed.
