I personally believe it will be far nastier. I have been anticipating no BC at all or they charge for BC. For example. A digital model for $399 and a physical card slot with BC for $499. Similar to how PS3 was initially.
I also fear somehow / someway BC is tied to Nintendo Online subscription. But we will see.
This is a far different Nintendo than before, I do not think looking at the past generations helps all that much.
Either way, the only thing I know is, I wouldn't expect something less than $399 and as I said, I have always expected $499 is the price.
As for the rumor, I do not believe it. I think the price range is possible. Nintendo is not going to charge small $50 to add physical. It would have to be a $100. Also, the release dates on a Tuesday seem unlikely to me.
So, I think this rumor is false.
