How do projector preorder prices usually compare with later sales?

Just preordered the new iris at $500 below the listed regular price, but it looks like shipping won’t start that long before Black Friday. Wondering if there’ll be a similar price or a better bundle by then. There’s price protection through December, but this is my first time preordering a projector, so I’m curious how launch deals usually hold up. Did prices change much once it was widely available or the next big sale came around? A small difference wouldn’t bother me. Mostly wondering how long the preorder price tends to stay a good deal.
