From what I have seen online about Magic Band +, they look amazing with some nice new features. There is no hurry in ordering a MB, so if interested in what MB+ can do, I would wait.
The idea of the golden statues talking just sounds fun.
However, it seems like Disney doesn't talk to themselves. It seems like one group is pushing hard to get rid of Magic Bands and forcing you to just use your phone for everything. Then, you have another group creating a new MB with new features that aren't available in any other way.
