While I'd agree the majority of vapors are still low wattage/voltage, but I suspect that is driven by two things, experience and initial cost... Once they get experience, I'm seeing them all over the place depending on their preferences or interests. I'm seeing a lot that go with both higher wattage and lower wattage depending on the atomizer they are wanting to use... but that perception is likely because it's my own interest so that is what I notice more.
The reasons for there being more low power/voltage users are pretty simple. The beginners aren't going to purchase a higher dollar mod at first when they can first try the lower cost options just to see if they suit their needs. Now that a higher quality single eGo type PV is in the $20-$30 range... why not simply start with something like an istick which costs in the upper area of that range if not a little higher. So I do expect more vapors to move to higher power units... but it remains to be seen if they will use those to their capability or not. Of course there will always be those that lower power don't satisfy their needs and they will migrate to the higher power ones. Then... there are those that just get caught up in it and always buy then next new thing whether they have a need for it or not.
My own interests now aren't about power/voltage although that is a consideration... what now interests me and I think is the next trend we'll see is a move to more ergonomic devices. It'll be a little bit before the vapors tire of the box mods that seem to be the current trend... but I do think they'll start wanting a device that is more comfortable to hold at some point. So I think the "more power" trend is starting to level out... and the next one is one of form as well as function.
We can't base our opinions on what we see on ECF. We still make up only a very tiny portion of the vaping world. I would guess the more hardcore proportion who are more likely to venture out into new areas.

That made me laugh out loud.
