I never got MP11, so I don't currently own that mould. I couldn't justify to myself buying MP11 since I already own MP03 "Greenscream" and Hasbro TRU Starscream... don't need a third MP Starscream. But when I saw MP Sunstorm I figured that this is a whole new character that I don't already own in MP form, plus I don't have any other version of the MP11 mould -- part of me wants to own the MP11 mould, but I don't want another version of a character that I already have in MP form. Also, I'm not expecting Hasbro to release their own version of this toy later down the track... so I'm suspecting that a cheaper Hasbro version is unlikely (not impossible, but I'm not expecting it). Pricewise, MP Sunstorm's price is 13650JPY, which is the same RRP as MP11, which I do feel is very expensive for a MP Seeker (it's $40 more than what I paid for MP03), but considering that it's a limited exclusive, I find it acceptable (not great, but acceptable).
I was saying to The_Scream_Man yesterday, when talking about MP Soundwave... I've only ever paid above $200 for two Transformers -- and both of their names end with "Maximus."I'm really not sure if I'm willing to go the same distance for a Masterpiece.
I reckon there will be. Hasbro's released their own version of every other regular store-release MP that Takara's ever done, except for Megatron (for obvious reasons). I would be surprised if Hasbro didn't jump on the opportunity to release a version of Soundwave.
