The third wave of TF3 Robo Fighter toys have been sighted in America, which are just redecos of first wave Optimus and Bbee.
Someone mentioned that they saw them 9 months ago (about when they should have been released), but might be thinking of the first wave versions.

We never got the Robo Fighter toys in Australia, so anyone wanting to complete the set (yes, that'd be me ), will have their work cut out trying to find these two, and at a reasonable price.

For those wondering what Robo Fighter toys were (since we never got them here), they are non-converting figures, that were about Deluxe size, with pop-out weapons like the Stealth Force vehicles. (basically the "stealth force" gimmick, but in robot mode)
The ones at the front of this photo...


Wave 1 - Optimus, Bbee, Ironhide, Starscream.
