Nooooo, I don't want MP's to go back to the days of diecast. It's so easy to damage the paint on diecast.
Anyway, just got Wheeljack. I actually transformed him perfectly without instructions or videos. I did however miss the mirrors included in the manual's baggie.
After them making a big deal out of the missile being fireable I'm sad to see it's a very tight pressure missile. Since Lego can fit a spring loaded missile in a small 1x4 brick I would have thought Takara would have the ability to include a spring in Wheeljack's launcher.
