This is an interesting concern. I’ve been following the issue from sources like this [1] and this [2]. It turns out the Microsoft is planning to finally pay full regard to the standards board that was in place before Microsoft joined the web.
Internet Explorer has been a very forgiving browsing environment, and therefore has been enabling shoddy design practice for a dozen years. Now the chickens may be coming home to roost as IE 8 (might) follow established standards and require correctly coded pages that will look and behave the same in all browsers.
The problem they have is to decide whether they can afford to initially alienate all those Microsoft-only website developers by implementing the international standard with their next release. It is the socially responsible thing to do, but there will be whining. Badly coded web pages will look as bad in IE8 as they already do in all the other browsers.
