Yes also our LHR JFK November flights (BA117) have gone from the 747 to the 777 with Club Suites. The auto-assign has also put us in 5EF which I would love to try.
Like others, this is great news, except that I don't think we'll make the trip (we continue to LAS) for Covid reasons. I hope the same plane sticks to spring 2021 when we are looking to re-book.
