The Nexus are just like the nWo. How long will it last?

I wouldn't say the Nexus are just like the new World order. There are similarities in that they are rebels, trying to "take over" but they are a group of Rookies that have gotten over as heels, working with top workers. The nWo started with three veteran workers that were all well-known. I like how the Nexus angle has gotten the Season 1 NXT Rookies over. As for how long it will last, it will continue for as long as the concept gets over. Not only are WWE officials pleased with what the program is doing for the younger workers, they are happy for what it is doing for John Cena's character. I personally think the Cena character has been a lot better during the program, much better than his watered-down "over the top" PG gimmick.
