Update: In the latest title update, the Star Wars Clone Trooper image has been removed from common_d9.rkv. The icons and banners remain the same.
I happened to look in the Game Room directory and see a big resource file earlier today. I figured that there might be some images in it that could give clues about future content, and there was!
First I checked for PNG headers files using a hex editor, then I used this Perl script to extract them.
In the image below, you can see that it contains a number of unused achievement icons (is that one with Pac-Man, Quick Man, and Air Man an achievement for “extra mans”?), new content pack banners, and strangely a picture of Star Wars clone troopers. Maybe that’ll be used to announce the original Atari Star Wars arcade game.

I’ll update if I dig anything else out of C:\Program Files (x86)\Microsoft Games\Game Room\common_d9.rkv.

I don’t know which implementation of 802.11n is to blame, but the Linksys WRT610N and WAP610N both crash when a wireless client using the Atheros AR9285 causes load. It’ll work for a bit of web browsing, but stream some video or download a large file and the router will reboot.
The Xbox 360 Wireless N Networking Adapter also causes the same crash, and uses the AR9280 chipset according to this press release.
Reflashing the router firmware (both devices are still on version 1.0), changing the MTU, and updating the Atheros driver did not make the problem go away. Brian Tillman had some luck when he replaced the Microsoft-supplied Atheros driver with one from HP, but that didn’t work for me.
I ended up switching my Xbox 360 back to a wired connection and setting my laptop with the AR9285 chipset to use 802.11g and that did the trick. Not an ideal solution, but the WAP610N I’ve got going hasn’t crashed once since then, and other 802.11n clients have worked fine.
