I'm curious about this, too but they do have this to say on the page:
"Whether they beep or speak, many of our favorite characters are ROBOTIC! Review Isaac Asimov's Three Laws because September's crate is packed with items featuring some of the most famous artificial lifeforms in pop culture!"
That narrows the character choice down substantially. Could be anything from Ash to Walter. Now it's a matter of what kind of merch it will be.
