Great boost WoW and YoY for NS, both in USA and WW. XBOne has a decent YoY boost and obviously an excellent WoW one, and it's second again in USA, but it's not enough to keep the second place WW it had last year, this year NS is too strong. PS4 has a small drop YoY WW, but a small boost YoY in USA and it's still first WW by a large margin, but much smaller than the previous BF. Anyway, things go very well for Sony and Ninty and more than decently for MS, no need at all for Sony to rush PS5 launch, the only thing PS4 really needs is better sales in Japan (although its current Japan sales aren't even vaguely as bad as XBOne ones).
Japan is a "special market", not easy to capture the attention of Japanese. They don't care about 4K, or massive power and teraflops, or spectacular graphics like God of War, Forza Horizon4, etc. They prefer to play their puzzle-games, sexy games, their j-rpg, and sure they prefer cool little lovely hardware like Switch, which is also portable. How to blame them ?
On the other hand, it appears that both Sony and MS don't care that much, focusing 95% on the West, and this is the result.
