Message Walls are definitely coming to UCP but they run on the same software (IDK if that’s the right way to phrase it) as Discussions and will not support Wikitext.

As for Wiki Activity I agree it is superior compared to Recent Changes because Recent Changes is a technical mess and confusing to look at. It’s improved slightly but it’s no Wiki Activity. Despite all the negative feedback Recent Changes has received they seem to be more focused on improving it instead of just bringing Wiki Activity over. I dread the day my wiki converts over for a variety of reasons but the loss of Wiki Activity is the biggest one.
