You forgot that Russia is going to take over after Trump gives them the key to the land and whether or not they'll allow it.
Also don't forget if aliens finally show themselves and gives out better crazy new tech. 
Also if JJ Abram is going to give a shot at taking Nitnendo movies.  That plays a big part. 

Oh I don't know, maybe use the speculation capabilities that you didn't loose at other threads that I'm sure you didn't have with all your other 2,794 posts.  Grow up.

One should be enough, no?

I would say two years of actual support from Nintendo and interested parties.  The Switch should be able to get cheaper by then.  Main point is, Nintendo won't start really pitching to the handheld audience until the Switch has a chance at success there.

The docks thing is just convenience.  If you have a smaller tv in your bedroom ou could take the game from your large living room TV to your bedroom TV.  Or if you have a game room but want to take your Switch to your living room to play a party game or something.  It's just easier than moving the dock every time.

Seriously? My post was just saying households would have a varying number of devices depending on their situation. Their is no "every house will have X NS's"

If you actually got offended by my post you should take a break.

Should be, but I live in America where just one isn't enough.  Specially when pokemon is involved.  Don't you get that Nintendo wants to sell these things many times to many people in the same house?  A household in japan with 3 3ds isn't very farfetch. 

Sorry, but from my view you kinda asked for it.  If that was what you were saying, that didn't translated very well.  Because, common, that's a very no answer answer you wrote. 

But you're right.  15 minutes every 2 hours, right?

Considering that audience is dissapearing fast (parents don't buy 2-3 handhelds because they cn just give them mobile phones), so aiming for a more core audience will help them. Also, there will still be people who buy multiple Switchs, but when Nintendo offers a handheld-only, dock-less version.

I don't see the issue, you choose what you want and that's thanks to the hybrid nature of the device, so the answer is it depends.

You can buy a couple of Switches for example and have a dock in the living room plus the others in the bedrooms.
The bedroom docks don't need to be connected to TVs, they could just be used as a charging craddles.

Depends on the household

Some games will remain single player like Pokemon so if both players want to play, then they will have to take turns or buy another Switch

I believe it is 10-15 mins every hour according to Nintendo.
