We probably wouldn't have Blu-ray movie discs today if it weren't for Sony. It championed the format, and Sony's PlayStation 3 game console led the charge. Sony bet on Blu-ray, Microsoft bet on HD-DVD, and HD-DVD lost. It's all ancient history now.
"It does not have a 4K Blu-ray drive," said a Sony representative when we asked.
Maybe Sony has bigger fish to fry these days. It's pushing virtual reality with its PlayStation VR headgear (coming October 13), and with streaming services like PlayStation Now and PlayStation Vue, perhaps Sony's betting that a cloud of internet services will be the preferred way to watch movies anyhow. (It might already be true.)
Even if Sony expects you to download those 4K movies instead of streaming them, it looks like Sony's making it easier to swap a new hard drive into these consoles than ever before.
It's just a little bit weird to watch this role reversal -- particularly when Sony's also been pushing 4K for so long.
