PCMag notes that Softbank CEO Masayoshi Son revealed in an interview with the U.S. Ambassador to Japan, John Roos, that Apple CEO Steve Jobs was working on Apple's next big product up until the day before his passing.

"I visited Apple for the announcement of the iPhone 4S [at Apple headquarters in Cupertino, California]. When I was having a meeting with Tim Cook, he said, 'Oh Masa, sorry I have to quit our meeting.' I said, 'Where are you going?' He said, 'My boss is calling me.' That was the day of the announcement of the iPhone 4S. He said that Steve is calling me because he wants to talk about their next product. And the next day, he died."

Really, could it have been otherwise?
