Warner Archive has announced that it will soon be offering Blu-rays. These will not be MOD discs, and will be pressed in limited quantities.
In other words, if something you like comes out, get it — who knows how long inventory will last. (This was the key to collecting laserdiscs back in the day.)
No idea how they’ll decide which titles get the HD treatment — the ones listed are not previous Warner Archive releases. The Command (1954), the first CinemaScope Western, is a nice-looking Warner Archive title — and it’d be a swell Blu-ray.
