I actually commend them for making him fit in with the scale of the others (since they have since changed up the scale) but I feel like it's so damned redundant. If you could trade in your MP-04 for it, I'd do that, but I've already got this figure, at about 25% bigger, and he cost less. As much as I like him, I can't keep doing this. In a line with only 8 characters (and about half of them repaints of a previous one) it's ridiculous that they're already remaking Prime, and it's the 3rd release out of 10! And he's not a $10 repainted Snake Eyes version #14 for the series, he's a $250 toy.
I'll wait for the Ultra Magnus update with the trailer armor, and then consider getting the scaled-down Prime.
He looks good, but unless they do a Megatron that's scaled down to match, then it's slightly annoying. And even if they don't, it's annoying! I would've been fine with the larger MP Prime and Megatron if it meant we got more characters. If he was $150, I'd maybe bite. Not at that price.
