It'd be so great if this update included something none of us were expecting. A total surprise! (As well as all the things we're anticipating of course!)
I really hope you're right. I already predicted some weeks ago that the update would be dropping after the wedding event, so I hope I'm right. We desperately need more content now.
I did not play much but followed the various events from afar and participated in some (Easter, the maze); overall it was disappointing. The last update took place two months ago, right? I think it's time to give us some good news. I think we will see the café, the diving, the improvement of the shop to a minimum. I hope for new excursions, with mini-games like in New Leaf (I miss this island so much!) And maybe new fruits? Durian, banana ... I can't imagine New Horizons without them!
I have been playing since launch many hours per day, but I am at the point now where days go by and I don't even play. I hope there are new updates, and I hope they tweak some things...like being able to craft multiple items and buy multiple items in the clothing store. Hey, I can dream right?!
I hope the animals can swim too! I don't see why it would be too difficult for them to create animations for the villagers to paddle around in the water.
