Heavy Rain Shown Behind Closed Doors At E3 2008?

Looking at the official Sony press release, first party PlayStation 3 titles that were shown at E3 are listed in the release. One PlayStation 3 title from the press release that has not had coverage is Heavy Rain. Is Heavy Rain being shown behind closed doors by Sony? If so, the press would likely have to had signed an NDA to keep quiet about the game. If anything, the game will probably be fully unveiled at the Leipzig Games Convention next month.
