Nobody will buy these iPadOS devices at those prices.
If they make them 16GB/512GB base config like with Macbook Pro 14 and 16 and let them run MacOS apps, then yes, they might, just might have a market share significant enough to make some money for Apple. Otherwise it will be instant flop.
...Still the price is insane, running MacOS on iPP has been technically possible since M1, artificially limiting it to some sort of M3/M4 would be...very Apple, in the despicable sense.
