I'm not as gloomy as you guys.
I think we'll see the same thing as other markets: the general RC model shops and also suppliers (like Graupner) will probably suffer. Niche/specialized manufacturers will offer stuff for the hardcore enthusiast. What was previously "mid range" will probably disappear.
On the lower end you'll get toys and ultra-cheap RTR (just like you said tobyker). At the same times, the Chinese also ship motors, ESC, TX/RXs for a fraction of what higher end manufacturer cost (and they can also output decent products provided you're willing to pay more than $20 for a TX, for example). I'm not going to lie: I nowadays order most of the electronics from China/Asia through eBay or dedicated sites (like Hobby King).
Now when it comes to models, kits, fittings, I think we'll have some niche suppliers with very narrow product ranges, quality products and ... probably some relatively steep prices. What you save on electronics, batteries, ... will probably be spent in those boutique shops.
Thanks to the Internet, a small manufacturer can sell worldwide.
There's also 3D printing. The cost of printers is still quite steep and it takes some learning both in term of 3D modeling and the actual printing. It's the kind of device that a club could afford to maintain, right next to laser or wood milling machines and scroll saws. Can be used to print actual parts or molds to cast resin for structural parts.
Anyway, model shop owners are probably in a hard place right now, just like many "brick & mortar" shops these days. There are so many products available; market is so fragmented, you just can't stock so much stuff. And with hot topics like drones, there's the same problem as with smartphones: every 6 month there's a faster, more advanced version ...
There's a small RC shop a couple miles from where I live. I doubt the guy makes a living out of it (in spite of what I consider steep prices - which I don't blame him for). And among younger generations like me ordering from the Internet is just the go to solution.
