We will have Lists and Polls in 4.0. We are working on Newsletters as well, but I am not sure whether will be able to deliver this module for the official version. Of course we will do our best to ship Newsletters module. With polls control you will be able to show multiple polls on a page with single control which is not the case in 3.x version where PollBox can show only one poll item.
All the best,
the Telerik team
