I don't know about new. I think the ps4 pro and slim have been discontinued, at least in Japan. I don't think they want it competing with the ps5 or something like that.
afaik, the ps4 pro was discontinued, possibly so it didn't compete with the ps5. however, the ps 4 phat and slim are still being made.I don't think any official electronics store have a PS4 for sale
I just checked for new PS4 Pro consoles, but they cost more than a PS5.I too have been looking for a long time, there is nowhere in my country. So if you really find where you can order please mark me
