A bit late, but I'm really glad they (Hasbro & FunPub) managed to get this happening again this year, as it would be a shame if it was dropped due to some immature vocal minorities campaigning for joke characters.
Since BotCon is only 5 weeks away, it will mean the nominations period is only expected to be about a week or two long, leaving about a week or two of voting on the Transformers site.
If you are a member of a global fansite that Hasbro has asked to participate, submit your votes.
If you aren't a member of a voting site, post here who you think should be inducted this year.
This is actually something I'm looking forward to now for this year, as it brings a respectable/formal element to the convention, to go with the all the "young fun" the rest of the event has.
(it wasn't included in the BotCon brochure, so must only be a last-minute thing.... and is likely to be part of the Saturday night party/event)
