I just bought two sets of G1 Walmart minibots from an Aus store, only to fund they have NO tech specs whatsoever and are the foreign edition. So I am now going to have to source a new set for mosc. Knew the price was too good to be true. It has a Hasbro rrp sticker of 14.99, which means that the set we will get at retail is probably no tech spec too 
Turn over the back Goktimus, I think you might have them too from the different look to the front packaging
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
