Looks like Nomura postponed his appearance at an event on the 28th. It seems the media assumed Nomura would be making his return to the talk circuit by the 28th. Event organizers told reporters that the event was postponed because Nomura needed more time to recover.
It appears as though Katsuya Nomura has canceled his special appearance at an Osaka event on the 26th. The media was camped out in front of Nomura's house again on Thursday and caught of glimpse of Sachio leaving the house early in the morning. It seems she didn't show herself in public after that.
A person connected to the Nomura's said, "I haven't heard any immediate plans for his discharge from the hospital, and I also haven't been told that he'd be returning today either.
