If they released them on DVD, they wouldn't sell as many Blu-rays. Simple as that.
By offering the series only on Blu-ray, they've got at least some people going "Well, guess it's time to upgrade!" Those people would be content to just stick with their old DVD players if they offered it on both formats.
See, I disagree completely with this. The industry should not drive change in technology, the consumer should. VHS died a natural death because DVD and PVRs were better. DVD should also be allowed to die of old age, not be taken out back while it's still in its prime and shot, just because there's a young whippersnapper with go faster stripes.
If the demand for TNG-R on DVD is there, then the studios should cater for it. I just wonder if the demand is there.
