My Steam achievements hadn't updated since late February. So I removed the account and resynced and everything that should be showing is showing (except for some game-specific problems caused by removed/renamed achievements - which is unrelated to this problem).

I can confirm this is still present for Steam achievements. The following achievements appear as both complete and incomplete for me:
- Nobel Peas Prize
- Towering Wisdom
- Better Off Dead
- Ask Me About Mustache Mode
- Home Lawn Security
- China Shop
Also the following achievement was changed when they had to take out the Michael Jackson zombie:
- "Walk this Way" became "Disco is Undead"
Edit: The video Krataur mentioned worked for me. It can be found here. However, if you go to the Quick Look listed on the Assassin's Creed Brotherhood page, or if you look up
Assassin's Creed Brotherhood on the Quick Look list, you get the ~50 minute one that gave me trouble.
I suspect it will be well worth the wait. My anticipation is great however. I just recently replayed the original to try out the ARG materials and see the new ending (also, because it was fun). If you are impatient for Portal 2 and haven't completed all the advanced challenges in the original, do so. They are a lot of fun and a few are real mind benders. (Unfortunately, a few are also tedious - but overall it's worth it.)
