I have to agree with part of ldcdc's comments. Reseller hosting is not going to become obsolete anytime in the near future. But i do believe that reseller hosting will begin to fade as more and more webmasters realize that it is not a great deal sometimes. As more and more webmasters decide that they want real hosting (with support..) they will draw business away from resellers.

The more business taken away the more resellers will begin to fail and close down. Eventually it progresses until resellers are no longer the fad of the internet
