I think we are in uncharted territory right now. Retailers are hurting and it is likely to get worse before it gets better, so that should create downward pressure on prices. On the other hand, the supply chain has been disrupted, so even if dealers have stock on hand, they may not know when they will get restocked, which would create upward pressure on prices. Eventually, I think we will see prices drop again if the situation stabilizes.
My sense is that right now the major dealers are taking a look at their existing stock and trying to clear some of it out in order to produce cash flow. There have been some great bargains lately on a few lenses and the Canon refurb store has let their sale run unusually long and offered extra discounts on some items. If you aren't too selective, but are looking for the best bargains, this is a good time to shop. If you have a specific item you are looking for, it may not be so great if it's a high demand item.
