Actually, I think it will be both. NextGen will make touring easier for those who fork over more money to WDW, not directly on FP+ but indirectly on the things needed (e.g. onsite rooms) to get the "good" FP+.
There are limited numbers of FP for attractions such as TSM, Soarin', Peter Pan, etc. Today, people get FP based on the amount of effort they put into it. Get to the parks early, run around from FP dispenser to FP dispenser, and get "good" FP. The single parent working at the local grocery store has the same opportunity to get FP as the wealthy business executive.
With NextGen, people who stay onsite will get the first crack at FP+. Effectively, spend more money and get better FP+.
Hey, if I spent $400/night on a Deluxe Resort room, I'm going to be on TDO's case to get me a FP+ for TSM. TDO isn't being evil; they are following the business rules of supply-and-demand. It just means those with more money to spend will have better WDW experiences. The haves will have more, the have nots will have less. It's the way of the world lately. If they were selling rice to the poor, it would be unconscionable. But they simply are selling vacations. Still, it depresses me. "Et tu, Brute?"
I do not know this for a fact but signs are pointing this way. It's also possible TDO will change this 5 more times before officially rolling it out.
