Well, only time will tell on that, and while I may or may not have doubts on that point, it's not necessarily a factor in decisions made now, but rather a gamble on the future. What is a problem now is that unless you are lucky enough to live close to one of the extant parishes, if you don't have an Anglican priest now who is willing to convert with you, you can get neither an ordinariate nor a WRO parish. Neither church is ordaining Anglican rite missionaries to start new congregations de novo. Even in church-thick central Maryland I would have to drive a long way to get to either a WRO parish (there was one in Bethesda, I don't know where they are now) or an ordinariate parish (Mount Calvary, wherever they end up). Practically my choice is limited to one of the local NO-Roman rite parishes; there's a couple of Orthodox parishes close by, but none of them are English-speaking (and at least one if not two of them is Oriental, not Eastern).
Being in Maryland you could try St Gregory the Great in DC, or St. Patrick in Lewistown MD. There are a couple in Virginia as well. In total between the AWRV and ROCOR there are over 40 at this point in 23 states and in Ontario Canada as well (where there are now 3). We have people who drive 100 miles to attend on Sundays. Of course it is a matter of how important all this is to a person. Other than Montreal Canada and San Francisco I don't think there is a major population centre in the USA that is more than a 2 hour drive from a WRO parish, mission or monastery. In Texas you could have your pick for the most part. Yes it is a gamble on the future but what is the option? Swimming the Tiber is not a gamble so much as a slow death sentence at the hands of the people who brought the "fruit" of Vatican II to the world.
