PS4 : 326k Switch : 171k X1 : 134k 3DS : 70k

On the software side (digital not included)

Hardware adjustment begins !

PS4 sold very well but Switch and XBO did lower than I expected.

Ps4 in it's 5th year is still dominating.

I know this was God of War month so obviously it was going to win NPD, but the Switch numbers are abnormally low.

edit ... Doh.

Thats a massive gap, certainly a turnaround from earlier in the year.

Switch HW is meh-ish. I'm interested in numbers for the Variety Kit and Tropical Freeze, hopefully they both did ok.

Edit:

I'm a bit surprised to see Xbone down there. Sure, it didn't have God of War but it did at least have Far Cry 5, and its last few months were pretty good.

Didnt expect PS4 to win by such a margin...

*edit:  damn thats actually more than both Switch + Xbox combinded O_o
            So God of War did have some kinda effect :P
            I can see a small boost carrying over into may as well from GoW.

Holy shit that is a major month for ps4. Sold almost 200k more then xbox in April. Beat switch very easily again and wins another month this year. Now we see folks why Sony don't drop the price. They'd be crazy to with numbers like these. God of war major system seller confirmed.
