Hmm, I admit I'm not 100% up-to-date on the latest WWE storylines....just that everything currently seems to revolve around Orton and Cena.
However, Nash and Goldberg certainly still have a presence about them that can still command attention.
The NWO years in the WCW was probably the last great plot pulled off by of that organization before Vinnie bought them over...but not sure if the WWE will re-visit that idea as they've spun so many cliques of their own since then (i.e. D-X, Evolution, Nexus, etc.).
Ahh well, we'll probably never know. We shall see soon enough :)
