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.
