I just noticed when asking about my calendar for the day, Siri now tells you the time, title, location, and attendees (and I'd assume any other information you put in an event). Before it would simply state "you have x events today". Not sure how new this is but it wasn't like this last week. Gotta be a server side update. Edit: it's even more detailed than that. I just asked how my week looked and siri read aloud all details of every event for the next 7 days. Edit #2: just notices it only happens when you do raise to speak...a feature I just turned on so for all I know it's been like this all along. This thread could be a giant whoops.
