The create/VIE/Backbone port is taking place in parallel in the D7 and D8 versions of this module.
D7 - branch: node/1808076-createjs-d7 -
D8 - branch: node/1824100-createjs-d8 - this issue
The difference between the two branches should boil down to how the libraries are included. We're pushing for create.js and VIE to be included in D8 Core. Backbone is already in Core.
@frega, @bergie and myself will work on finishing this at http://groups.drupal.org/node/256573 next week.
