I've never seen the arc called anything else besides Millenium Falcon, but yeah, it reminds me of Star Wars everytime I read it as well.

I don't really mind when they decide switch arcs (provided, of course, this isn't the last one), so long as they throw Guts back into the picture. I'm with pretty much everyone else on this one: the manga really needs to return focus to Guts. However, maybe this is a ploy to draw even more distaste towards Griffith, by making him the center of attention for a bundle of chapters.
