maksutov - I think it will either die out or go more mainstream eventually, but it will be a long drawn out process, and I don't expect it to seriously dwindle in the near future.
This.
However, I would add that it is difficult to tell what will accelerate the process. The organization appears to be in something of a positive feedback loop at the moment, and if that continues, it will have an effect on how quickly either dying out or mainstreaming takes place. At the moment, I don't see they have a way out of that loop. They need capital to reorganize things to keep their long term finances sustainable, they are pushing for this capital, and doing so unapologetically, using the internet, (and other sources, of course). This is going to ruffle a few feathers if it keeps up.
Secondly, social evolution forces all authoritarian organizations to capitulate to either outcome you mention above. History demonstrates this over and over. The information age itself has caused massive changes in society as a whole, (just look at society's recent acceptance of gay marriage, marijuana legalization, etc.), and while organizations like the WT have previously been better able to isolate themselves from outside influence, it is much more difficult to isolate themselves as such today. Their own significant internet presence even makes that isolation that much more difficult. This is yet another commitment they have made that is almost impossible to back out of, socially or fiscally.
What it will come to in the end, is that if they don't mainstream, they will die out. Social evolution will force this process.
