Template suggestions for node.tpl.php are effective only after specifying content type.

OK, I'm not a dev, but if anyone is looking for this kind of functionality, here is a solution - replace function entity_view_mode_preprocess with this code (exclulding opening and closing php tags):

<?php



/**
 * Implements hook_preprocess().
 *
 * Add template suggestions for an entity based on view modes if they do not
 * already exist.
 *
 * The eventual order of the entity's theme suggestions are:
 * - entity-type__bundle
 * - entity-type__bundle__view-mode
 * - entity-type__id
 * - entity-type__id__view-mode
 * - entity-type__view-mode
 */
function entity_view_mode_preprocess(&$variables, $hook) {
  // @todo Improve checking of entity type based on hook. Some entities do not
  // match 1:1 like file_entity and user_profile.
  if (!empty($variables[$hook]) && !empty($variables['theme_hook_suggestions']) && entity_get_info($hook)) {
    $view_mode = $variables['elements']['#view_mode'];

    $entity_type = $hook;
    $entity = $variables[$entity_type];
    list($id, , $bundle) = entity_extract_ids($entity_type, $entity);

    $suggestions = &$variables['theme_hook_suggestions'];

    // Ensure the base suggestions exist and if not, add them.
    if (!in_array("{$entity_type}__{$bundle}", $suggestions)) {
      // The entity-type__bundle suggestion is typically "first".
      array_unshift($suggestions, "{$entity_type}__{$bundle}");
    }
    if (!in_array("{$entity_type}__{$id}", $suggestions)) {
      // The entity-type__id suggestion is always "last".
      array_push($suggestions, "{$entity_type}__{$id}");
    }
	
    // Add view mode suggestions based on the location of the base suggestions.
    if (!in_array("{$entity_type}__{$bundle}__{$view_mode}", $suggestions)) {
      $index = array_search("{$entity_type}__{$bundle}__{$view_mode}", $suggestions);
      array_splice($suggestions, $index + 1, 0, "{$entity_type}__{$bundle}__{$view_mode}");
    }
    if (!in_array("{$entity_type}__{$id}__{$view_mode}", $suggestions)) {
      $index = array_search("{$entity_type}__{$id}", $suggestions);
      array_splice($suggestions, $index + 1, 0, "{$entity_type}__{$id}__{$view_mode}");
    }
	
	// Add view mode suggestions based on entity type.
	array_splice($suggestions, $index + 1, 0, "{$entity_type}__{$view_mode}");
  }
}



?>

Last line implements/hacks in functionality I was looking for.

PS. Sorry but I don't know how to create patch (yet).
