I really hope that they don't do that personally.
If there is something that is a constant in wrestling history is you can't keep going back to the well, even Hogan the biggest draw of all time only got a few months out of Hulkamania again before it got stale.
The wrestling business needs to keep evolving and keep moving forward, if you go backwards you are basically saying your product sucks so lets go back to something that worked 15 years ago.
Not only that the nWo isn't the nWo without Hogan and Hall, neither of those guys are going to the WWE so whats the point?
The nWo worked because it was 3 big names in wrestling basically taking over an organization. If they made a new stable, had HHH, Nash and Punk together then it would work but don't go back to the nWo, its old news and personally one thing I can't stand is when wrestling companies are so unoriginal they have to do stuff that worked years and years ago.
Besides, if they DO go this route I guarantee in 2 weeks every fan on this board will be complaining about it.
