I finally got my copy of Ketsui Deathtiny earlier this week. And it seems to have received a new patch today. Have the trophies always been in English? I swear they were in Japanese earlier this week.
Also menus use the western button layout for confirm and cancel now, pretty sure it's in preparation for the western release. Hopefully it means the import version will receive English localization too.
The trophies definitely were NOT in English when I played.
