The fan-vote ends today (American time), and Hasbro have posted up some new (last minute) info that might have changed the vote of fans....

Q: Aren’t Needlenose and Tracks brothers? A: Yep! And, you’ll get a glimpse into what drove them apart and led to them joining the Autobots and Decepticons in the War for Cybertron trilogy! Get Excited!

Q: Why antoher Wheeljack figure, we recently got him as a toy? A: Wheeljack is one of the few Autobots whose Cybertronian vehicle alt-mode is seen in the original 1984 pilot episode of “The Transformers”. This version has never before been created in toy.

Q: Why does Impactor wear a Decepticon logo? A: Much like the bounty hunter Doubledealer (who bears the Autobot crest), Impactor wears faction logos which do not align with his true nature as a Transformer. You’ll learn why and how he came to wear the Autobot crest, instead, in the untold stories of the War for Cybertron Trilogy.
I don't know where these were posted, but it was mirrored here.

Based on the response about Wheeljack (having his Gen1 Cybertronian mode), it suggests that the winning toys will be completely new designs.... and even more of an annoying tease that the losing four will not be made (or else, what would be the point of having a fan-vote to decide what toys will be released).
