Developing Customizations for VB4 CMS
 

So I'm interested to find out how flexible the CMS is as far as developing customizations goes? (eg. Drupal type 'modules')

Can any dev or knowledgable preorder'er fill me in?

Custom content types? (not blogs/articles)

Different views? (instead of always displaying teasers)

How likely am I to be able to jump in and start developing what i want ontop?
