After seeing the video review last night of MP-13 while it was up (i saw 95% of it while it was up then it was down), I'd SOO buy this too if it were to come out. While MP-13 looks cool (and its on preorder and i'm happy we are getting an official one), the alt mode's back is ridiculously kibbly! i wonder if his sample was missing a cover or something. the G1 altmode is far superior actually. The legs can't move back at all (not sure if acoustic wave's could or not either though), and the legs just look too plain and not toy like enough (way too cartoon simplified which i guess is hat they went for but the or original toy had a nice distinctive leg shape). FT-s versions (both the firsrt and second prototype) seemed superior in some ways.
