I totally agree based on history. I predicted that for the Sandcrawler, Sail Barge and ISD before the refreshes were made public after seeing what happened with the original 7778 batcave which was night and day better than it's replacement. Now for refreshed sets like the original Batcave and Sail Barge, their values did slowly appreciate again but it took time. plus their appreciation rate wasn't now where like before.
based on history, even original sets that were much better than their refreshes didn't rebound quickly. ISD, Sandcrawler, Batcave, many batmobiles, the original sopwith camel, etc... took a while for values to stop decreasing, stabilize and appreciate.
