Not surprised to hear anything about Angel Beats on the localization front to be honest. Sekai Project does want to translate Angel Beats while, from what I hear, Key has stated they're open to seeing more of their games receive an official translation even if not by Sekai Project. However, both have stated multiple times they're waiting to see how well Clannad does in the west first before they consider Angel Beats or any other Key game for localization.
Even then, I hear the game's text count is so large partly thanks to the amount of choices available in-game I wouldn't be surprised if we didn't hear anything about an official English release until after all six volumes are out in Japan.
