No.
It is in the manufacturers best interest to sell the product at a price which nets them the most revenue.
What if the math works like this...
Sony sells 4million at $50 profit, or Sony sells 4.1 million at $0 profit. Obviously consoles have a revenue stream outside of the hardware, but that doesn't mean that the hardware can't be part of the revenue stream. Just because consoles have launched as loss leaders in the past it doesn't mean you should expect them to continue to do so in the future as shareholders don't like to see quarters where they lose billions.
Also, as more and more consoles are bought for reasons other than games, you can't made the assumption of selling a $600 box for $400 and make it up in games. Remember that the PS3 was for a long time the cheapest and best Bluray player simply because Sony was effectively subsidizing its cost to the tune of $220. In is new world, that can't happen anymore.
