I'm on Team There Will Be No Major Anniversary Update.
I am interested to see what updates might come out now that they have all the holidays released. This upcoming year will be the make or break year for the live service model.
Exactly my point of view. I hope they take notice of the criticism they've received and change their update-plans. After all, they also added cloud save by popular demand. Nevertheless, I'm pessimistic in regards to the future updates - so that I won't be disappointed again.
Nintendo would have teased a major update at least a little in the last trailer, instead of just hinting at Mario-items.
