It may depend, though. Freedom has no TV deal but it has a dub (edit: although, it seems the Blu-Ray release from earlier did get a dub track, so this is likely a moot point). I think there may be some Bandai Visual influence at work, but I wouldn't count out the economy and current market as the dominant factor. BEI did cut some staff a ways back, and extras are limited compared to before. There's also the fact that the last time they dubbed a show like this it was Lucky Star, and that didn't go well. They may be doing okay, but they likely can't afford multiple situations like that at this point.
Well, as I noted at ANN, if you're going to do a sub-only release this is a good way to do it. Streaming is already up, the release is timed with the announcement (right on time to be sold at Otakon--well played), and there isn't long to wait for the whole thing to be available.
