I'm not sure, don't have PC Gamer yet here. One thing to keep in mind though that NF takes place like 3 (2?) years after Prophecies (its the manuals timeline section). I feel like GW:EN will only be a few years in the future just as NF is, and thus the changes caused by the passage of time should be negiligable (ie the Magnama Jungle suddenly won't be a desert). Some stuff could happen though (for example, Kryta under a new government).
