I think they look kinda hot.
I'm rather intrigued by this Magnesium Alloy and chrome plating they're using, rather than Aluminium and annodising. It'll be interesting to see how the finish holds up.
I don't think Magnesium alloys are nearly as dense as aluminium, which might make them rather light too. (Then again, the old trigger an body were plastic, so they might just compensate for the reduced weight in the frame area.)
