Are you sure about the Lucky Star OVA? Rightstuf lists the format as Hybrid, in contrast to "English subtitles" for a title like Toward the Terra.
On subtitles in general, I can only assume it comes down to cost-cutting and playing things very conservatively to make sure that they stay afloat for the immediate future. Which I can understand, especially considering that Sola and True Tears are BVUSA holdovers when you get down to it.
That said, they need get assertive again eventually. 2008 was a great year for them, whereas this year it seems like they've been very quiet. They can get by on 00/Geass/Gurren Lagann for awhile, but of the three only 00 will be a fresh release throughout 2010. Titles a step below (in terms of fame) like Kurokami and Freedom will also finish this year.
I'm hoping for a good Otakon and/or Anime Expo from them. Even 1-2 new A-grade acquisitions would give me confidence that they've still got it.
