After the update, I appear to have fewer apps in my drawer as well, and noticed that the apps you mentioned were not there, I found them in a Games! folder I had created, but am about 80% sure I did not put it there. Perhaps it automaticly moves this to any folder name Games, etc. Check all of your folders to be sure, if it shows in your Settings | Apps then it has to be somewhere... otherwise, try uninstalling from Settings | Apps, and try re-installing. Also check to make sure that they are not in the Secure Folder, as a possibility.
