Yeah we will probably see a decline in GPU prices over the next 2-3 months. Bitcoin ming is no longer profitable using consumer equipment (GPU) so Etherium has been the reason why GPUs have been so expensive.
And Bitmain just launched it's crypto miner https://shop.bitmain.com/product/detail?pid=00020180403174908564M8dMJKtz06B7 which basically blows away current GPU mining so once they can ramp up production, we should see prices drop and loads of used mining GPUs trying to be dumped everywhere.
However nVidia will be releasing their next gen stuff soon too so who knows what MSRP they will set it at.
How do you figure Nvidia will release their new cards soon ?
