I'm in the minority, in that I feel disappointed.
It pretty much copies the transformation of the original Metroplex in both modes, so hasn't utilised 25 years of engineering and design advances, to make something out of such big square limbs (as mentioned above, the city mode should have had stuff folding out to fill up space, instead of just looking like a robot doing the splits).
If anything, it has made Gen1 Metroplex look better, because this one has a "stomach" section added in to make the robot look more humanoid in proportions, but has then ruined the other two modes by not collapsing that - it looks wrong having the top half sticking up so high with a huge gap in the middle. The Gen1 version had no gap, so both alt modes sat lower as one block.
We know Hasbro (TakaraTomy actually) can engineer giant toys well (look at Primus and Unicron)... this is like a step back, almost like they've sacrificed a good transformation just to make the robot mode look good.
I think they are trying to provide an interactive "playset" (especially in the city mode), but it is still a transforming toy, so I think it should still have a bigger emphasis on the conversion element, so that the different modes, look more different than a robot sitting down or doing the splits.
Optimus Maximus is a good example of Hasbro producing a "playset", that totally sucks as a convertible toy.

I'm also disappointed that all these FOC toys are coming out so long after the game, which will make them harder to sell - lines that don't have a cartoon, movie or game out don't do well. This could leave us with shelf-warming, making it less likely we see later waves, or this big one that's still six months away.
Hasbro should have had the toys coming out in the 3-4 months before the game release while all the hype was out there and the promotion of the game, so that these sort of bigger ones (Metroplex and triple-changers) were out soon after the game, and then sold out by Christmas.

Pricing is likely to be close to $200 here, which is cheaper than Fort Max reissue (which has a more complicated transformation into city mode than this), so I think this one will be compared to that when it comes out.
