My honest opinion - Robot Heroes. Initially a line for the toddlers, similiar to that of Star Wars Galactic Heroes and Marvel Heroes. They have given us G1 already and plan to do so as well with the movie characters. They are simple, affordable and well...kinda cute lol. The fact they make different generation based ones will help. Kids new to TF may collect a few G1 Robot Heroes then start turning their heads to any left over classics figures who are the latest thing on the market that resemble G1 characters. The same goes for the movie toys. Buy the Robot Heroes, the kid in intrigued now they want the voyagers, cyber slammers, fast action battlers etc. Not only that but even collectors seem to be digging these little guys.
