Quick questions about MP-01 Prime and g1 packaging

Question #1:
I heard that the figure was rereleased, and I'm not talking about the one that comes with the trailer. Is there a difference between the original release and the refresh release? Probably not any differences on the figure, but maybe the packaging? I want to buy an MP-01 Prime to keep sealed but I'd like to have the very first release. If there's no difference in packaging or figure then I'll be just as happy with the refresh release version, but if there's any differences, even minor I might want to just go with the original.
Question #2: For the g1 packaging, is it pretty easy to get the little insert trays that hold the figures? I don't want repros though. I'm thinking about getting a boxed g1 figure but it doesn't have the insert tray so it wouldn't display very well without it.
Thanks in advance!
