It's pretty clear to me that the new clone looks more like the animated version than the movie version, and that the 2003+ SA release is more in line with the movie clones.
But you know what, we all see different things! That's fine. I remember when people thought Monkey Leia was the best thing since sliced bread. I won't be army building the new clone but that's me. Especially at these prices. Nobody needs to get offended over anyone's opinion of the new clone trooper. We're supposed to all be chiming in our thoughts in these threads, that's what they're for.
I'll be the voice of indecision here. Each figure appears to have its own merits. The most notable "flaws" with the TVC Clone are the legs. They appear to be too long and too thin. However, the sculpt captures the angles and the lines in the armor better than the 2003 sculpt. The 2003 Clone has a certain bulkiness to it, that is more appealing than the thin nature of the TVC clone. The TVC helmet looks far more accurate from the front, while the 2003 helmet sculpt seems to more accurately portray the the helmet when seen from the side. The shoulder pads on the TVC Clone look to be too high up, but I like how they partially hide the shoulder joint.
TVC Clone wins hands-down for weapons. It's awesome to get a new blaster and a larger, more accurate rifle.
If something truly angers me about the new clone, it's how it stands out from the old mold. Both are solid figures, but they might as well be based on totally different characters. I'm still unsure if I'm going to mix the two sculpts together, replace the old clones, or just army build the new clone a little bit and display two separate Clone armies. I don't think I'll be totally replacing the 2003 SA Clone since I'm so used to seeing it in my collection, and I still absolutely love the figure. It's very cool that Hasbro decided to revisit the Episode II clone, but hopefully they don't update OT Troopers such as Biker Scouts or Snow Troopers.
Chewie, the upcoming 501st Clone Trooper appears to be the new clone sculpt with a different helmet. It's a damn shame that the ROTS white and Utapau clones were released with the Gelagrub body, especially now that this new sculpt incorporates the hips articulation and removable helmet while improving aesthetics and adding wrist articulation.
