Because Switch is selling well and Nintendo would be leaving a lot of money on the table by going so low on the hardware price when they absolutely don't need to.
So basically greed is your answear?
Nintendo already sells and makes decent profits on hardware.
A 149$ Switch TV, would also be sold at simular profits amounts.
Why would nintendo sudenly become more greedy, and sell it higher?
Because it can? it wasnt happy with current profits? This could move alot of units I think, which would equal more software sales, ect.
I think you are ignoring business sense. The question is why would Nintendo sell a $149 Switch that will sell well at $200 or $250? A Switch TV version would only sell to specific people, as most people want the hybrid thing. So it's not like a cheap TV-only version of the Switch would unleash monster sales. Just like a $100-off Switch Lite didn't release monster sales because most people want the hybrid version. Probably about just as many people would buy a cheap $200 SwitchTV as would buy a $150. Those are both very cheap systems. The difference is one makes way more business sense for Nintendo.
For people who have no interest in using Switch as a portable, they're gonna naturally go for a SwitchTV over the original, especially if it improves the performance of games slightly and has a bunch more disk space. $50 off the main option or $100 off the main option is already a great deal, making it $150 off would simply be a bad business decision for Nintendo as it would lose them a lot of money.
"it wasn't happy with current profits"...ummm all companies want to improve their current profits. It is a for-profit company. Let's just say you should never run a business with your attitude.
You're literally saying a SwitchTV should sell for $90, because a stand alone pro controller costs $60. That makes zero business sense. What makes sense is a standalone SwitchTV selling a bit cheaper than the Lite, because it would be a bit cheaper to make, then add $60 for the pro controller. So we get $220 or $230. Also Nintendo would want to sell it for as much as they think people will buy it for, see how the sales do, and then lower it if needed. They couldn't raise the price later if they realized they put the price too low.
