First, it seems the Sirius-XM merger will happen.
Second, recent Met moviecasts will appear on EMI DVD. This is going technologically backwards: anyone with a HD DVR could already capture (and, with a bit of know-how, burn) a (somewhat compressed-for-broadcast-feed) 1080i HD version of these presentations. To sell just the non-HD 480p version (that is, DVD) without a simultaneous HD offering (that is, Blu-Ray) is at best uninspiring.
Sometimes the house recognizes it has a tech-forward audience, and sometimes it doesn't.
UPDATE (7/30): A commenter indicates that Blu-Ray versions of the moviecasts may arrive in September as well. Budget for that Playstation now...
