It's not clear from the first two posts, but I think this is the week that Switch passes PS4 in total sales.
up to April 282019 (Famitsu)
Switch 8,042,166
PS4 8,047,754
April 29 - May 5 (Dengeki)
Switch 52,171
PS4 21,448
If you add those numbers together you get this
Switch 8,094,337
PS4 8,069,202
Of course these are from two different sources. Don't know if anyone has the lifetime Dengeki numbers up to April 28, 2019.
