Yes, but MadWorld was meant for the west since its inception. It came out here first, and when MadWorld released in Japan, I don't even think SEGA had a hand in it. Could be mistaken, though.
There's no way Virtual On Force will be at E3...Vanquish MIGHT make a slight appearance, but nothing major. There's not even that much in Japan yet, and even though it gets a worldwide simultaneous release, I think in Japan will probably get the most attention.
