Interesting.
A wizard has granted you a wish, but a very limited one.  You may gain a sum of money equal to the profits from the next major thing from a franchise.  Do you want:
Final Fantasy 14 
Call of Duty ((Whatever, no idea what they're on here))
the next Bond Movie
D&D Next
See you'd be crazy to pick D&D Next, regardless of the quality of these various things.  Whereas you could probably legitimately throw AD&D 1E in there as something that you might consider, adjusted for today's money of course.  
The hobby is just very niche.  It has a strong and active niche, but it's just a niche, and it's not breaking out of it.  
If it's any consolation, wargaming with miniatures is in an even smaller niche
