A:AnswerThey're not. This is misinformation that has been affecting the internet. The only reason you would be paying 90 dollars is if you live in the EU and thats different currency all together.
A:AnswerNope. A lot of people are making this assumption, but it is similarly priced everywhere, not just the US. Sadly, inflation is an international issue. Overall, $450 USD isn't too bad, about what I expected, but I know a lot of people are frustrated that they won't be able to afford it right off the bat.
A:AnswerThe 5080 has an MSRP of $1000 which is double the S2's price and won't be cool enough to run in a smaller form factor without being cut down a lot. Nintendo and Nvidia haven't fully disclosed the chip they are using yet but leaks point to similar amount of CUDA cores to the 2060. A lot of the graphics throughput especially in 4k is going to be driven by DLSS AI upscaling rather than raw compute performance which will be on game devs to leverage.
A:AnswerWe don’t know, so check back. Yes, I would take limited stock into consideration. You are always free to order from the Nintendo store. (I have to use Best Buy since Nintendo doesn’t accept PayPal.)
