Weirdly, MouseMisers.com has updated 2011 basic
DDP and QSDP brochures, dated 12/10/10, that look official but the original August releases are still up on the Disney site. (The DxDDP list is there too but gives a "corrupted file" error when I try to open it). The updated copy includes both Teppan Edo and Yak & Yeti (along with everything else that you'd expect - the 2011 list matches the 2010 list plus Via Napoli and La Hacienda).
I wouldn't be surprised if Disney updated the list somewhere, like maybe on their TA portal, but neglected to update the general public link right away. We see it happen all the time with park hours. But since I'm not familiar with MouseMisers at all I'm not sure how confident to be in their information.
