According to NeoGaf posters from Japan who are generally pretty reliable it's not terribly difficult to find a PS4 on storeshelves.
I think they still will sell 200k-300k first week. Even the Vita and Wii U did that.
It's after that where sales will slow a lot ... not a whole lot of Japanese centric content for the rest of the year unless Square-Enix miraculously delivers a Final Fantasy XV (good luck).
