I don't have a crystal ball but I don't see any price changes coming from Pulsar in their current line up in the next 6 months. These new monoculars have only been on the market about 6 months and they made a couple price adjustments early on but it seems like everything is set in place.
The only way I could see that they'd be lowering their prices on these models would be if FLIR/Armasight came out with some new models in January at the SHOT Show that were better and cheaper than their models. The issue with that is, even IF (and that's a big if) that happens, it's likely those new FLIR/Armasight models wouldn't be shipping until early Spring at best. So again, all pure speculation, nothing will likely even be a possible competitor to the Pulsar units for 6-7 months. Then at that point, you are 6-8 months from a new product cycle coming again with new optics and better pricing. It's like buying a computer, new smart phone or other electronic device, you can end up waiting forever to buy because there is always something better and/or less expensive around the corner.
As for Black Friday/Christmas sales, that's a good time to buy, but if you are looking for price alone, you will probably end up buying from a big corporate (online or brick and mortar) store. They don't get love from us smaller guys who are trying to hack our way through the business jungle by providing customer service and support that the big boys can't. I can say with confidence that any of the NV dealers that frequent this forum will provide you with 100x better customer service and support, before and after the sale.
So in closing, without a crystal ball, I'd say that the prices should remain steady for the Pulsar units for the coming months, other than some holiday sales. Another option would be to beat the bushes on the secondary market and buy a used monocular, but by doing so, the warranty will not transfer to you, no matter what the seller claims. Neither FLIR nor Pulsar allows warranty transfers, but it might be a way to save some money on the front end as long as you are willing to take the risks.
Oh and I'd definitely go with an XQ38F right now over a FLIR monocular. That could change next year but again, it's technology, the only thing constant is change.
I hope that info helps you a little bit. Good luck!
