Will there be a FormBuilder equivalent that enables us to define the data to be prompted for?
FormBuilder does a lot of work behind the scenes, like initializing fields with given values, allowing fields to be edited if requested, pattern matching, etc.
Such a tool would be very good to have, though it would probably be difficult to implement given the stateless nature of the new bot API.
Nothing to announce just yet but we'd love to create an updated version of FormFlow for v4.
Closing this as the Bot Builder Community has released a FormFlow implementation for V4: https://www.nuget.org/packages/Bot.Builder.Community.Dialogs.FormFlow/ with source here: https://github.com/BotBuilderCommunity/botbuilder-community-dotnet/blob/master/libraries/Bot.Builder.Community.Dialogs.FormFlow/README.md
