Will file sharing repositories become the new 'app stores' in the next 5 years?

Thingiverse IS a Makerbot creation anyway. My opinion is they understand most people don't have CAD skills and they intend to alleviate that.
But people will soon see that there is a huge difference between a 3d model and a 3d printable model.
Also, there is so much it is getting a bit unwieldy. More work to organize ans check the stuff ? But in that case can it remain free ? We'll see.

I hope the majority of designs remain free. My opinion is really good designs should be able to be purchased for a small download fee so the designer gets rewarded, like the app store model. However, it has to be cheap enough for people not to hesitate about paying for the download. When designers are charging $25 per download like on cubify before they took down their marketplace it was just plain greed. I would pay $1 for a download if the design was good.
