If I hadn't already bought Maximus at Big W (and admittedly, had the fun and satisfaction of an early release) I'd totally buy the SDCC version. I'm astounded that it came in at under Big W retail, considering how much it is to ship it from RK.
I really hope they get the other SDCC exclusives. I read speculation that Brainstorm might not see a Hasbro single release... Windblade looks gorgeous in blue.
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
