I love the concept, but the transformers looks a little wonky. They should have gone with some kind of masterpiece level design... then you would have the best of both worlds. Neat idea, but not sure I will cave in. The thunder machine looks cool though
Couple things for the idea of a Masterpiece level of design.
1) Right now the price is already pretty high, and sales don't look to be all that great with each release going on sale/discount (Soundwave hasn't yet but he will). Trying to go even more detailed/intricate would increase the price even further. I don't imagine there is a large enough market for $200US+ offerings. Also remember that the Masterpiece line has a large Asian fanbase as well that probably wouldn't be anywhere near as big if it was Joe/TF crossovers.
2) The designs are already pretty intricate for what they are, and I don't know that further engineering would make much more difference. Remember there is a point where you can't do anymore with a product due to plastic tolerances, and design/model requirements. Unlike the Transformers who were designed from the start to be able to convert from robot to vehicle, none of the Joe vehicles ever had that mindset behind them. So to shoehorn in a robot mode after the fact means that unfortunately there are going to be sacrifices no matter what. As well as making them be able to hold figures in vehicle mode. Masterpiece or not.
In the end this line is one of the best things going right now for me and I love it. Especially since we are getting new O-ring figures as well with each release on classic cards. Soundwave is by far the best of the three released so far, and maybe part of it is also the designers getting their heads around the process. So the first couple of releases are a bit wonky, but now they are starting to hit their stride and better know what does, and doesn't, work for making these toys. Bumblebee is a pretty good design as well considering it is an open air vehicle that has to hold figures. Unlike other "car" Transformers which have closed roofs and windows/doors, the AWE Striker has none of those to help with hiding stuff during transformation.
Can't wait to see the Triple-T/Kup and Mobat/Optimus Prime. Hopefully one of them gets revealed soon.
