Sony is posting profits and recovering from their financial issues, but they still need to remain in "save mode". Cut every corner, save every penny. It's not ideal no, but the company has to ensure its own survival before anything else.
What if psvr flops? That's a huge financial hit that Sony can't make back. I'm not saying it will, but they need to prepare for that just in case it happens.
I own a small company that was going down with the price of oil. We had to restructure, lay off every employee (10 of them to be exact), and invest the remaing funds into potential new work. Nothing was producing, but we struck gold and found some really good work. We recovered all the money we lost and are back on our feet. We hired two contractors to get the work done. But we still have to be careful with money, because you never truly know what's around the corner. A company running lean can eventually offer more jobs than a company that went bankrupt.
