Sony never really made their money back in console sales alone. They tried in 2006 with ps3 prices. They sell their consoles at a loss and make it back in software and services. They can launch ps5 at 299$ and still make money. They aint losing any money with ps now and ps plus its mostly all gain.
Yes they do lose money on consoles, no big deal but to maintain profitability there will be a limit to what they can sell the machine for. They will want to get the payback in say, 2 years. if they are taking a 200 loss on the machine and on average (via game sales etc) they make back 50 a year it makes the figures hard to work with. If they only take a 100 loss on average each machine is in profit in 2 years.
So, yes, take a loss but keep it in check with an aim to recoup it in a given timescale.
