In the past, it has been common that new hardware with low initial supply fetched premiums that lasted until supply met demand. It's not dishonest to assume that it's the same case here.
While we could decide to write some software that could pull today's market prices and update tables and graphs dynamically, we just decided to settle on a single number. If you are settling on a single number, the choice is either market price on date of publication or MSRP. Given that other GPUs tend towards their MSRP as time goes on, we decided to choose MSRP.
By the way, the MSRP for a regular 2080Ti is 999$, the 1200$ is the Founder's Edition price.
GPU modules are manufactured in China. Their harmonized codes are covered in recently established tariffs. 10% tariffs are already hitting cards arriving at US ports. This tariff will increase to 25% on Jan 1.
Prices will stay well above MSRP.
It's been a long time since GPU prices have been anywhere near MSRP, it seems dishonest to assume that they will be in the near future.
