Well $349 PS4 is up for debate if they slap in a 1TB HDD for the base console, that's increased perceived value for the same price if they hold at $399. But a 1TB HDD probably only costs a few $ more than a 500GB, which means Sony could make the 1TB standard and drop to $349. Though I think 1TB + $369 would be a sweat spot for profitability and accelerated sales. Then next holiday you have a massive $70 price cut to ramp up sales even more and get yourself a 20 million year.
There is absolutely no way Xb one goes back up to $399, at least not for the base console. That is $349 and can only go lower. However I do see new release bundles selling at $399. Halo 5(Physical) + Tomb Raider(Digital) bundle can be $399 and sell a shit ton. FM6+Something can also go for $399 and do well. But I think MS will either keep running with MCC or ACU (not likely) as the base sku at $349. A base Xb one at $399 would kill off Xb one sales even in the USA, and they need USA to sell well, along with UK to be in a decent 2nd position.
