Personally, from the wording and promotion of this by Hasbro, I get the impression that the fan-vote is for the next batch... which would just be two toys this time... and as some people have noted, these have all been reissued already - one very recently. It would make it more exciting to have at least one that hasn't been done.... like the JP Dino cassettes.
I'm actually more annoyed that they are making fans vote choose between Skywarp and Thundercracker, preventing people from having the three Seekers (for those who are new to the original series toys and just got Starscream earlier this year). It would be like being asked to choose between two children (if you had two or more)... Starscream needs both of his wingmen.
