I do not want to speak for Ski, but it sounds like the response here was all in relation to the current FP window enforcement at WDW and that no one has seen anything discussed like this for DLR. So it is fair to say that as far as we know there is no plan to bring this to DLR.
Further, since the erroneous news reports have been bouncing around then some like Ski may have felt compelled to try to shoot them down with stronger language.
In general I would not be surprised if they do start enforcing FP windows at DLR. And I would not be surprised if they don't. Some knowledgable folks on the WDW forum seem quite convinced that the enforcement there is completely or almost completely due to the coming XPass system whereby WDW resort hotel guests can book ride reservations far in advance like they can dining reservations. To make XPass work it seems like FP window enforcement is more important.
Since DLR caters to a different group of visitors - many more day trippers and many more locals - and has far fewer resort hotels - the idea of XPass at DLR seems much less workable. Therefore the importance of enforcing FP windows is just not there.
I think some of the folks around here - probably Ski included - understand this and come down on the side of it not making sense for DLR. And with no rumors about DLR out there then it just seems to be a non-issue.
As for XPass and the NextGen system - it sounds atrocious to me. Making ride reservations 6 months in advance the same way one makes dining reservations? Yuck! What a way to regiment your day. As if their ADR system is not enough where you have to choose which parks or hotel restaurants you will be at months in advance. Having some people who pay more to stay in a nicer hotel receive more front-of-the-line privileges at the parks? Big mistake for Disney IMO and something that would create negative feelings from other guests.
