Lobuk:The sword is just an effect, we've already seen it in the trailers and it's no where near that size. As for Dante's size, I like seeing a skinny Dante, when I see him in DMC4 the first thing I thought was, "ok, Dante's been built up way too much". I'd rather a character look slender and fast then like he can punch out a side of a building.
I rather have a beef-up Dante then someone whose on the Nicole Richie diet...
