I think the cost cutting was done in the right areas. Poseable fingers need to be like MP Starscream to be worth it - IMO the ones on TF1 Prime are pointless for posing anything other than a fist anyway. The splitting of the tyres is a minute detail i wouldn't have expected them to do.. and the extra hinge on the cab steps wouldn't add much either. Perhaps those features could be added back in for a MP Movie Prime....
