Which of the wysiwyg modules will get in to the core of Drupal 8?
Dries answered this in From Aloha to Ckeditor on Jan 02, 2013:


  Therefore, we are going to switch from Aloha to CKEditor for Drupal 8
  core. By making this switch, we will not only have a more mature
  WYSIWYG editor, but we also free up resources to work on other parts
  of Drupal's authoring experience. The CKEditor team has committed to
  fix the 8 functional gaps that we've identified in their two next
  upcoming releases.
