I agree, a Titan sized Devastator could be cool but everything's a guess at the moment - besides price.
Metroplex was simple now?
To weigh in again: it could be a G1 reissue, but if it is, why would it be sold in the Generations line (as the most recent product listing indicates) rather than the Platinum line where literally all other G1 reissues appear to be going? The same question applies if it's a redeco of TF2 Devastator (which I still think it could be). On the other hand, the moulds may have been designed to be sold separately later: for example, they could be recoloured to match TF2 Devastator. It's not Hasbro's usual MO, but if the size is the USP, they might go for it - it's not like they haven't been experimenting with all aspects of the marketing lately.
I still wish it would be a gift set of new molds. I think the new combiner wars stuff is at least to some degree a statement from the new design team, to the fans and third party companies: "hey, even we have a strict pricing structure and cost control, we can still make some cool official combiners!" And after giving us all these nice new combiners, they'd decide to entertain us with a G1 devastator, might as well drop the whole combiner wars in the first place.
As suggested above the new molds can be sold separately later, either as repaint or remold, or in a gift set again as convention exclusive, to make up for mold costs.
So according to a source on TFW it's an all new mold of voyagers and one leader and is the size of Gen Metroplex
I'm not 100% sure, but I think that source has proven to be good for information in the past, too - I certainly recognise the name although that could be from too much lurking on TFW. I really hope it is a huge, articulated, new figure on a par with Metroplex. Having the two battling on my shelf would be well worth the cost.
Apparently yellow redeco for SDCC??
This sounds like exactly what every adult collector would hope for - which usually turns out too good to be true. On price alone, would it be viable to produce something potentially double the cost of Gen Metroplex and risk deterring large segments of their main target market?
