What released on PS4/XBO to cause that spike in June 2015?

PS5 is about to outsell the Master System (20.84M)
Xbox Series is about to outsell the PS Vita (15.82M)

Batman Arkham Knight, which had a Limited Edition Bundle for PS4. 

All three current gen systems tightly clustered in America, but what stands out even more is how close PS and Xbox are in Asia.

Nooooooooooo not my beloved Master System.

Damn, I wish I had a NES when a kid but my mom bought the wrong videogame and brought a Master System home and I was too ashamed to say it was the wrong videogame.

It had some really good games in it though.

Thanks kazuya (& @trunks)

Just bought the Arkham games on Steam, didn't realise it was that big a deal.

Not bad for all consoles

Just some leaks and rumors but apparently a lot of big companies are moving to the new chip nodes and are leaving a bunch of capacity for 7nm. Consoles are supposed to sky rocket in supply pretty soon.

I know Sony already said they planed 18m for this year. So who knows if next year they can be in the high 20's.

Switch is winning this race, and it looks like it is about to leave the other two consoles in the dust.  This corresponds with holiday 2018 which is still about 1.5 years before the Animal Crossing/COVID sales explosion.  They aren't ever going to catch the Switch again.

Every system did fairly well this week, but YTD Switch is still ahead of the other two systems combined.

NS up and dominates as usual
PS5 up by a nice amount and back to 2nd place
XS 3rd, but up too
Nice week overall
Since the 9th April tie, PS5 on average outsold again XS, although by a smaller margin than what was able to achieve in the past, stopping the long period started on BF when XS on average outsold it. Could it be the end of supply issues or will we have to wait some more time watching PS5 and XS alternating good week to barely decent ones when supplies have hiccups? Meanwhile, Ninty keeps on reaping the benefits of being more frugal on chips.
