Here's an interesting interview Siliconera did with a few people from Cave regarding DeathSmiles, it's U.S. release and the possibility of other games, and a brand new game they're developing with a "world-wide" release in mind:

Fans looking forward to seeing the possibility of more Cave releases in the U.S. and maybe elsewhere will be glad to know they're looking into it:
MA(Makoto Asada, producer): Cave is definitely looking in a worldwide direction for the ports of our arcade titles, like Mushihime-sama Futari, EspGaluda II and other games.
They're also planning on releasing a new game on the Xbox 360, too. I'm banking on Princess Debut 2, you heard it here first!
