Producing one package - a dual format set - gives a company the benefit of maintaining the overall savings to be had from producing a large or fairly large print run. If you split that into two separate packages, then the savings are slashed.
From our perspective as customers, the Blu-ray is there if we upgrade in the future - DVD players do break down and need replacing and the small difference in cost now means many will get a Blu-ray machine when that happens. For those who already have Blu-ray, the DVD can be useful to play in other devices, a PC or laptop maybe.
BTW, I've hard it said that if these April releases do well (TOO LATE FOR TEARS & WOMAN ON THE RUN) then they're looking at putting out HIGH TIDE (1947).
