I guess it's OK to talk about it without Chris kicking our ass now. Dave Winer has posted some that Microsoft is going to show off IE 7 at GnomeDex on Friday. I've also heard that there may be tablet-based demos too, but I'm not 100% on that.
On Friday you'll see how deeply integrated RSS is in the architecture of the browser. But that's just the tip of what may turn out to be a very big iceberg. The people at Microsoft noticed something that I had seen, only peripherally -- that there were applications of RSS that aren't about news.
I'm a little surprised that Dave saw non-news applications of RSS only "peripherally". I guess it depends on how you define "news".
