could be... so far all the pics i've seen were right shoulders.
i also noticed that the part where the intakes/thighs latch onto in fighter/gerwalk are metal on the new 1/60 whereas on the 1/48 it's plastic. personally, i would've preferred they kept it plastic coz its a friction part and it'll be annoying when the paint starts chipping coz this part is visible in fighter/gerwalk modes, unlike the other metal parts w/c are hidden in all 3 modes... 2ยข
