The large Titan 12-inch toys were recently found at US Retail (Optimus, Bumblebee, Steeljaw), and on one of the Hasbro sections of the Transformers website two of those Titans (Optimus & Bumblebee) have been found as Electronic versions... similar to the TF4 Movie Titans.
The official images are mirrored here, with a couple of comparison images to show us that they are the same mould, and almost identical paint - Optimus is the same, while Bumblebee has paint missing on the knees.
The big decider is the inclusion of weapons, which the non-electronic ones don't appear to have.
Each one has at least 15 sound effects or phrases... hopefully of the Voice Actor from the cartoon.
