@Christian, seems the EF-DL will hold true for many years to come unless someone or a group of developers makes a start on a core system. And I'm not talking about enterprenuers/business agents because they are just that ( like I wrote earlier nothing wrong with this ). In the meantime, many other smart vendees of these systems will make them free with features and the developer cms industry will eventually disappear. This whole problem is the creation of the free-software empire and the "evils" its brings. Slowly but surely real developers will not exist in the future except on very different platforms. 
 
Me thots.

what you forget is that it takes a LOT of time and money to develop a
cms from scratch. see: http://www.ohloh.net/p?q=cms

eg:
drupal core $ 2,442,947, 44 Person Years
joomla: $ 12,744,398, 232 Person Years
plone: $ 3,435,840, 62 Person Years


I doubt that you can compete with this ;)
