I was under the impression that Konami already owned them? So this just sounds like Hudson's properties, such as Bomberman, now belong to Konami. So we'll still be getting their titles; it's just the brand name that will be no more (outside of Japan). This doesn't seem as bad as it could have been, but it's still kind of sad to see long-lasting companies disappear.
Aw man... going to really miss Hudson. Amazingly, they were responsible for some of my favorite releases, including the Bonk series on TG-16, Bloody Roar (with Eighting), Bomberman of course, Adventure Island... wow.
This is Hudson's US branch. I can't think of much they did offhand, besides XBLA Bomberman, maybe? I know Act Zero was Japan. It seems like Hudson Japan still exists. I wonder if Lost in Shadow really, really bombed. It didn't even have a chance to sell yet, though, right?
Also, wasn't the Mario Party team folded into the restructured NDCube, which made Wii Party? I think Nintendo is fine with Party games.
