250m LTD?
Are you predicting that Switch is going to sell less than the 300m predicted by that guy whose name I don't remember for Wii U?

Yes, it is secondary target, but you sound like you talking generaly about Switch sales not just about those 150m sales.

Again, Switch will have sequels and sequels can be quite different compared to previous game (BotW is very different compared to Skyward Sword), same like new IPs, 3rd party exclusives, 3rd party games..

Its not how its work, saying that people who wanted some franchise already bought console is totally wrong, you have different people with differrent preferences, for instance, you have some people that want to buy Switch to play Zelda but they think price point is still high for Switch, than you have some people that want to play Zelda, but they want onother Zelda game at least, or you have some people that want to play Zelda but they want much more exclusive games for system (I mean instead Zelda you can put any other game), than you have some people that want more game like Diablo 3 or Dark Souls to play them in full handheld mode, or more games like Octopath Traveler, Bayonetta 3...you can take example of PS4 with God Of War game, IP was already on PS4 but new GoW in despite GoW 3 was on PS4 gave huge boost PS4 sales in its 5. year on market.

Difference is that Switch is essentially handheld hardware, and plenty of people see Switch like handheld on first place and they dont want to gave $300 for Switch when for instance they know there is PS4 or XB1 with one game for $200. Also difference is that Switch can sell like device per person (like every handheld can) while only home consoles cant, and Switch still has high price point for such a selling, just example family with multiply kids, hardly that with $300 per console they would buy 2-3 Switch units per house, but with price point $150-200, that way more possible. Talking about revisions, Switch will have multiply revisions and different price point, including low price offer similar like 2DS was for 3DS.

Dont forget, Switch is NIntendos unifed platform, so they have much more options for support because they will suporting just one platform, so like I wrote, that means new IPs, reviving old IPs, much more 3rd party exclusives, ports/remasters of great games from past console, sequels and new games..

But that what you fail to see, similar to 3DS, Switch also dont have real competition on market, point that all consoles can sell great in same time proves that. Also when you comparing Switch and 3DS, Switch is selling much better world wide than 3DS in same time period whithout huge price cut or revision like 3DS had, it's much healthier platform with much stronger sales.

Like I wrote, only DS and PS2 reached 150m, so that will be incredible hard in any case for any console including PS4, but Switch can easily pass 100m+ at least.

This "joke" thread will seem funny in a very different way when the Switch passes the PS2 in lifetime sales and then keeps selling.

Nah, switch will be luck to cross 100M mark, most likely going to make 3DS numbers, 70-80M.
PS5 and Xbox scarlet are coming, and they are going to steal switch momentum.
Since Switch is a "secondary console" for most in the US ( https://segmentnext.com/2018/08/09/nintendo-switch-secondary-console/ ), when ps5/scarlet arrive sales are going to drop as people starts to buy the "main console" for next generation.

The biggest hurdle the Switch needs to clear is attract players who not not apart of its core audience to grow its user-base. If it can get a huge-selling game that isn't a traditional Nintendo power-house like Pokemon/Smash/Animal Crossing/Mario/Zelda/etc that will do wonders for it.

I was certain the user that made these 200M+ predictions for Nintendo HW was perma long ago...

Well 250M is very optimistic to say the least. 

Are we allowed to talk about John Lucas?

250mil+? This is sarcasm right?

Actually Switch can be easily seconday console even for PS5/XB2 owners also, Switch will have much bigger effect like secondary console than because it will have much lower price point, something like $200 compared at least $400+ for PS5/XB2. Current $300 price point dont make Switch best secondary console, especially when you can often buy PS4/XB1 for $200.

300+ if a switch with smart phone option launches in a year or 2

Wait. Are you saying that the Switch will sell 250 Million units in it's life time? Did I read that right?
