The Corn State (officially Hawkeye State) is coming to ATS soon and with portion of Official news (like review of Cedar Rapids, river ports, agriculture and even live preview) we have also some leaks and speculations. Now we see the map of the DLC which is looks realistic.

I assume that we see the release in the end of June-beginning of July right after ATS 1.55.
