Well the jury's out till we get the toy, the same applies to Sunstreaker and Megatron (cause I don't have one yet) to see what sort of complexity they use to justify the price hike for each toy.
To be fair to the designers I think the beast modes look pretty good considering what they are trying to achieve. I'm really struggling to think of any organic looking transformers that have lithe organic beast modes with this level of articulation. Robotic beast modes aren't held to the same scrutiny so no comparison there. Some of the larger rounder box shaped animals maybe, but I don't think that's a fair comparison. Characters like Cheetor, Dinobot, Airrazor and Blackarachnia are always going to have make sacrifices for their organic beast modes.
To be fair to TT, you're just paying for plastic and size in a Titan class, there's minimal parts and bugger all engineering in them, their transformations could be done in a Legends toy.
