I have pondering this ever since I saw the first film. No Ark, no Teletraan, no Space Bridge. I still find it a tad sad that they haven't been worked in, at least Teletraan. I'm sure Teletraan could be built by Ratchet (or Wheeljack if he ever shows) in a central Autobot HQ, even if its only a giant datatbase that holds TF knowledge and can perform certain tasks only a Cybertronian computer can do - locate space bridges, TF activity etc. Would Teletraan be welcome or is it too late to worry about it?
