I think maybe we are talking past each other? They haven't implemented the anti ice fix yet. The feds point blank told Boeing not to submit the application for final certification for the 7 and 10 until the nacelle anti ice fix is done.
The in house rumor is they are using the same engine nacelle but with different materials to satisfy the engineering requirement. It still has to be implemented and tested and then certified. I think a year is pushing it, especially with Boeing being put back into the crawl phase of crawl, walk, run after falling on their faces repeatedly.
