The lack UHD-BD is absolute nonsense to me. As far as I can see the Pro only exists due to some mandate from Sony top brass to push 4K. That's the only thing that explains this ultra-narrow, razor focus on 4K displayed at the meeting. But yet it won't push UHD-BD, which is fucking strange considering Sony owns a movie studio and sells the damn things, and is actually involved in yet another format war (HDR10 vs. Dolby Vision). It's a borderline incomprehensible move. It's taking a feature away from the machine, a feature its competitor just launched with.
