You'd know how to spot photoshopping more than me, but the recessed details, really looked separate like the outer shell has perhaps a "plug" of "greeblies" to give a more deep look to it?
I was thinking the arms on the head and the one on the torso looked separate too, and those ankles I could go either way, but it looks a lot more separate than Legends R2...
I have a hard time imagining they wouldn't put the arms on the dome... Seems like a major part of the character to me, from the short videos shown so far.
If it's just the dome and shoulders, that's a shame. Still a fun little addition because droids are what they are (I still buy up ASP-7's in bulk), but a shame the arms could be axed.
