I was JUST going to make this thread. Logged onto GAF for that exact purpose.
Here are some notes of interest:
-Gamefaqs has Sept. 1, which was presumably a placeholder. This has been replaced with oct. 1, which I can only assume is another placeholder.
-IGN had a release date set for yesterday
-most worrying, mastiff's website has "late summer" for technic beat, yet "early fall" for gungrave. Gungrave has shipped, and technic beat (obviously) hasn't
EDIT: From GFAQS:
