I don't want to be that guy who points out minutia, but the title alludes to a news event that isn't true. Bezos clearly states in the article that Amazon has "not yet figured out the grocery model," but the title makes it seem like it's rolling out outside of Seattle.
I was at that shareholder meeting, and Bezos was answering a question about the future of Amazon Fresh asked by the only other person under 30 in the room of 100.
Bezos didn't make any pronouncements with his response. Instead he praised the Amazon Fresh business so far, disclaimed progress against inherent difficulties in that market, and said out loud that he continues to believe in the business and management. There was nothing else to get out of his answer, and any reporter or other 'source' reading into that quote is speculating.
For context, Bezos also said he is optimistic about AmazonLocal and said similar positive statements when asked by an elderly woman who uses the service. I happen to know that the team supporting Amazon Local is much, much smaller than it was a couple years ago. Reducing headcount isn't what I would call optimistic, but Bezos was doing the right thing and saying positive platitudes at the shareholder meeting.
Two other people asked Jeff to comment on political issues -- one on the prohibition of selling gun parts, and another on selling violent video games. I almost feel bad for the man having to deal with that nonsense.
Amazon may very well be rolling out Amazon Fresh elsewhere or using the same infrastructure for same-day -- who knows -- but Jeff certainly didn't make any announcement or hint at the shareholder meeting.
