One of the TF3 exclusive sets announced at last year's BotCon was a 2-pack of Deluxe Topspin and Deluxe Leadfoot. Topspin would have been a redeco (noted as being called Twintwist), while Leadfoot would have been fully decoed with Target labels, as it was going to be the only US release of that mould.
In the end, Deluxe Leadfoot was only released in Japan, without any sponsor logos.
This 2-pack on ebay has Topspin in its normal colours (toy and picture on the back), while Leadfoot has all of its sponsor logos. It even has a Target exclusive sticker on the packaging.
The name of the set is "Autobot Team Racers", with a street diorama packaging.
Each comes with its regular mechtech weapon. Pics can be see here, as they have been taken down from the ebay listing (it sold for $300).


So, what does this one on ebay mean? Either the 2-pack is back on for release, or this was just a pre-production sample used for promoting it to Target execs, and is now the only one in existence.
Time will tell, if more of these appear on ebay, or in stores in America within the next couple weeks. If we don't see any more within the next couple weeks, then I guess someone owns a one-of-a-kind set, including one rare Deluxe Leadfoot toy with Target logos.
A sample first surfaced July 2011 after it was revealed at BotCon and SDCC, and another sample appeared in September, so maybe this set has just been sitting around since then.

I'd like to see a fully painted Deluxe Leadfoot toy released, to go with the set...
