Damn you, Mario, you beat me to the post...
Well, something interesting about the small period in which they talked about Four Swords, is that he mentioned connectivity. I'm not sure if this is DS-DS, or what, but that got my attention.
I also think it's kinda funny how he states that Wind Waker's graphical style (cel-shading) is harder to pull off then the new Zeldas more mature, realistic style.
