AFAIK, ICS does not support moving the actual apk (the app) to the SD card.
HOWEVER, you still can save the app data on the SD. In other words, while you are forced to keep the ~50 MB apk file on the phone's internal storage for a large game like NOVA 3, when you first open the game and it asks you to download all the playable app data, THAT can still be saved on the SD so that you don't clog up your phone's internal memory.
