To be fair it kind of remains to be seen how successful all of those are, long-term (I kind of expect Microsoft to exit the hardware console business at this point).
The Switch is also 30%. Unless you contend no console will be successful.
I guess we'll see if RAM prices come down any time soon. At current price increase rates I think no console stands a chance in the next few years.
What is "long term" to you? Playstation is more than 30 years old and Xbox is more than 25 years old. Steam is over 20 years old and PC gaming hugely pre-dates that. How long do they have to exist before you'll accept they are successful products?
Fair, maybe "long term" wasn't the right choice of words, I meant more like "indefinitely"? But I guess that's not really fair either since nothing lasts forever.
