I wonder if they will give the aliens an extra chest piece to make the ribs and onther organs and have those tube things on their back. I actually hope they don't do that, because that will probably make the aliens look to fat. It could somehow ruin the design, just like it was ruined for the Terminator endoskeletons minimates.
Anyway, that's my opinion. When it's about minimates, I'm really no fan of to mush extra parts if it can just be painted on.
