I plan to buy the toys though I hope to scale back from last time. In forming my collection statistics, TFM to almost 10% of my collection, not very far behind Classics 1.0/Classics 2.0 at all which to me just doesn't compute b/c I don't think the figures are worth it. Unless the toys see a marked improvement, I shouldn't be buying as much. I plan to buy all Scout through to Leader and perhaps Supreme size. Anything less or periphery (Legends, FABs, Slammers) will remain on the shelves.
I also plan to avoid a lot of merchandise unless its Robot Heroes but even then it'd better be good for me to warrant buying it. Last time I got sucked into the blasters which though fun (and were crazily cheap) I have no real purpose for or Robot Replicas (knock quality Revoltech) or stationary/posters and the like.
As for the toys, I chose option 3. As much as I want new molds I understand the necessity for the characters to preserve their looks to develop the brand of TFs. It just wouldn't make sense making wholesale changes to the toys. New weapons, different angles on alt modes etc.
Also I really hope we get better than subpar paint jobs and then having to go buy Premiums.
