Sony?s Yasuhiro Ootori revealed in a recent interview with 4Gamer that the PlayStation 5?s design actually helps to keep costs down.
The PS5?s height allows Sony to reduce the number of mounting boards. If the console was made wider and shorter, it would make it difficult to have a single main board, and would require the company to have a double-board configuration with a main board and a sub-board.
