Yeah, I wouldn't blame anyone for just hanging onto Siege Jetfire and skipping MP Skyfire entirely. I've pre-ordered this toy, but totally understand others who won't. This must be the second most expensive TF ever other than HasLab Unicron (that toy's RRP is likely to be unbeaten for quite some time (if ever)).
Most likely because Skyfire's design is 100% Floro Dery Sunbow cartoon, whereas MP52 also has to resemble a real-world F15 Eagle; so it's got all those real-life panel lines etc. Since Skyfire's design is entirely fictitious, it's gonna be plain as Jane. Also, they want to offer something different; if you want a more detailed looking Skyfire toy, then Siege Jetfire has you covered (and for a fraction of the price).I must say that I'm not a big fan of the pouty lips on MP Skyfire's face. Hopefully it will look better IRL.
