It's interesting to see that the Perfect Strike battery pack thing is being included with this. This suggests to me that we're going to see a Launcher/Sword Skygrasper MG so that we can create the Perfect Strike MG.
So if you want to display all 4, you would need to buy 4 MG Aile Strike Remaster + 1 Skygrasper MG.
I guess it would take a super hardcore Seed fan to really do that..
MG Aile Strike
MG Sword Strike
MG Launcher Strike
MG Perfect Strike
I expect for a MG Freedom Remaster and MG Strike Freedom Remaster to follow suite after this guy get's a release.
