Yes, ResV will be profitable for people.
People are always looking for a quick fix miracle that will cure that decrepit catcher's mitt they call a face.
Should you go after it? Depends. Can you handle the competition of clawing over the hordes that always follow the next big thing?
The vast majority can't. They make the attempt, get thoroughly bitch-slapped down by the l33t "ubers" banking on everything they touch due to their large budgets and more importantly, their skills, knowledge, and experience.
If you're a true n00b or even a fledgling marketer, avoid the "hype" and go for cornering the markets that may seem less profitable at first glance, but are far easier to dominate.
