I am fully expecting Larian to present their new and functional stealth system, announce that Shove is now a full action and can be used to knock enemies prone and inform us that a maximum of one spell of 1st level or higher can be cast per turn.
Those would be my wishes as well. I would also hope for a new chaining interface - not change to underlying system itself, but a better interface allowing us to chain individual characters easily, and preventing characters from randomly switching places.
