View mode for specific bundle Drupal 7 makes it quite easy to create a new view mode (see this tutorial for instance), but is there a way to define a view mode that is only available for a specific bundle (content type)?
No.

View modes are specified per entity type, not bundle, as hook_entity_info() shows.

It is also not possible to define extra fields which are only available for a specific bundle/view mode combination, only per bundle.
