update:
That is an error. It's being corrected.

His blog-post now reads: " New Bundles & Accessories" instead of hardware, in the posting he made.
So to re-cap:
1) no new hardware for gamescom.
and
2) they dont plan on doing a normal Press Conference Gamescom event, instead their going to "stream" video a Inside Xbox episode.
