Start saving... Attending or not, as a whole, this may be the best set we have ever done. Def in top 3 based on concept/mock ups

@mrlumptastic Top 3? 2006, 2011 and 2012... Other sets had good unique pieces, but maybe one feel flat here or there.

@mrlumptastic Really don't think there is a bad piece in the 2012 set. Every one of them would make a great stand alone piece.

Now for the hint(s)... Three are seeing their first updates ever, and what an update(s) it is!

For two of them, we have drawn upon the "distant" past... what that means will be known soon enough!

@GeneralTekno We are not doing TFA for 2012...

Trailbreaker, Gears and Brawn...

are NOT being done by us.

They need the good ol' Hasbro Classics treatment first and foremost... We'll take care of some of the other, equally awesome characters!

So let the speculation begin. Personally.......come oooooooooooon, Sludge!
