No, we haven't received any information. I suspect the Studio has (for now) postponed it. Perhaps because several players couldn't play Bake a Cake while their teammates could.
All we can do is check the game every now and then to see if the event has started.
I depend on my team, I need the bakery for my boosters! I think they're doing this to force players to buy boosters and I refuse to do it! I now just come on here once a day to see if it's open.
