I don't think this price has ever been attractive. It seems to me the right pricing most consumers are willing to take the leap for is 400.
If you really want to be honest the right price is actually $299.
However, its clear that at $399 the current gen consoles did better in 2013-2016 than last gen consoles did at that same price.
I think the market is read for $499. I also think that price will be dropped within 18 months.
