No. The PS4 is not.
Uhh... What?
If by past consoles you mean Wii or PS2 then yes. But I'd hardly say something is a failure or cause fit worry if it isn't trending as well as the two fastest selling consoles ever. That's like saying somebody failed because they got an A instead of an A+.
Yes it was PS2. Which halo end to be the best selling console of all time. But the US and Japan are the only markets where PS4 is tracking below PS2. WW it's actually tracking ahead and that's even with the PS2 numbers all being factory shipments and the PS4 figures being sold through to consumers. It's not exactly a 1:1 comparison given the release schedule and tracking metrics available for both consoles.
Yes I understood. No worries. I was using your post to further clarify on why it was unlikely we would see those sorts of numbers.
