From 4th March 2017 to 31st December 2020 how many months do you count? Are you sure it's about 3 years?

So, you believe NS will sell 40M in the first 4 years and another 40M in the 2 or 3 subsequent years? You're aware that no console in history sold in its first 4 years as much as in the remaining 2 or 3 years, right?

Xbox 360 did.

You're right. My bad.

Well, that means Wyrdness is expecting NS to do the same. That's very interesting. I'll wait and see.

I don't think Switch in its entirety is one system anyway, it will become an ecosystem of hardware IMO, so I mean traditional console cycle "rules" that we have (ie: not being able to sell as much in year 4/5/6 as 1/2/3) simply may not apply.

Because Nvidia is basically doing all the hardware chip R&D for Nintendo and it's a mobile part that basically has a new iteration of chip every 18 months, IMO Nintendo has options available to themselves that simply weren't possible with systems like Wii or Wii U, where the chip was so custom that making a better version of it would've required a fat R&D cost that would've been all on Nintendo's shoulders to pay. Nvidia's Tegra X2/X3/etc. are chips that would exist even without the Switch. 

But SFIV is the better game, it looks great, Capcom could push 1080p/60 fps, and asses can get kicked.

Essentially, Capcom chose the game with less sales potential and selling it at a ridiculous price.

No console has been a hybrid Switch is not strictly a console, it caters to two markets the console and portable markets and one of those markets Switch will be the only device for consumers to buy. Vita and 3DS consumers have to go somewhere for traditional portable gaming and right now they total around 80m plus (around 90m by the end of this year), that's a large pool of potential buyers Nintendo has no one else fighting them for and will make up the bulk of Switch owners, any console market consumers will be a bonus but in the end I see a around 80m users for switch.

In my inner circle we are 4 friends with the Switch (and another one will buy it this summer). We all bought the Zelda BotW and we all will buy the new Mario Kart game. I don't care this is a port or whatever. I also enjoyed "The Last of Us" and "God of War 3" more that many PS4 games.

I am sure Switch will be OK till September.

Any games..
Big impact MK8 Apr/May
Little impact USF2 and Minecraft in May
Modest impact to surprise impact Arms in June
Splatoon 2 big impact July/August

Zelda Update should be there somewhere in July/August too

But we need a surprise at E3 for September/October

It's basically the MK8 month as it is going to release at april 28th.

On top of that, isn't Minecraft supposed to be big?

Fire Emblem Warriors is likely in September
