When will Internet Explorer support RSS?

If you ever doubted that RSS is going mainstream, here is another proof that it is. Poynter reports that the Firefox web browser will integrate “RSS feeds as “Live Bookmarks,” so folks who browse the Web with the bookmark sidebar open can have headlines displayed in that familiar context. Firefox also supports one-click RSS feed subscriptions if the website embeds a link tag in the head of the HTML document.”

Apple has previously announced RSS support directly in the Safari Web browser. How long before Microsoft will include RSS in Internet Explorer? Maybe they already are. Anyone who knows?
