Well It appears from the two prototype pictures that devestators mouth opens for the turbine function. Granted its going to be with the sweet sinistar esq sculpt in the final version. Good demonstration of possibility. Does'nt look as bad as he had at toyfare. I'm actually becomeing really interested in getting one of these playsets as a display for my spychangers. Essentially Its a new transformers base in general. Hav'ent had a real base in ages so even if I don't go for RPMs the talking devestator base should be solid. Display some of the mainline robots around it. I think its worth getting. Except for the skids RPM. RPMs have hot packageing though. My wallet would weep if I went into those.
