Would be cool if they reach 100m hardware and 1 billion software at the same time.

Doesn't the 3DS have a much higher install base than the Switch?

So do NES, PS2 & Wii, can you figure out how they are completely different scenarios?

Well, PS4 is only 2-3 years younger than 3DS. You don't seem to consider the PS4's age vs the Switch's freshness like you would with the 3DS. What's the big difference? Is it just a matter of convenience?

Not age, place in the market.

PS4 still gets a ton of huge releases and is selling amazing, it just had its best year last year with 20m sold.

3DS is a dying platform that peaked like 5 years ago and hasnt gotten a single million selling title this year, software support and hardware sales have dropped considerably.

Oh okay. 

Such a big difference in instal base and considering average console attach ratio on 10 per console at end of life it's pretty safe to say it impacted total SW.

Individual games aren't much impacted by installed base, but total SW certainly is.

My comparison is to show how important digital is becoming for Sony (which I mentioned).

Switch software sales are irrelevant to achieving that goal, just saying 43% of PS4 software is digital shows that clearly.

Or better yet compare the current digital % to what it was in previous quarters/years.

There is a thread dedicated to that in VGC.

Basically PS4 have the win in most games, but some genres Switch ties and some others it wins.

Also shows that the userbase and even difference in time to release didn't made that much of an impact in most games distribution of sales.
