I have an opinion.
Sony knew the massive backslach they would have gotten, but what they want is to test the actual impact on sales.
If this flops very hard, there will be a price cut and PS6 might cost $600.
But if it's not the massive flop that it could be, and it meets the probably low expectations... there is no going back, Sony is moving on to full Apple mode and Playstation will never be remotedly affordable anymore.
