After hearing Biyomon's male voice, I think I'd have preferred them make him a girl instead. There are so few guys on the voicing staff, they start to sound the same. Merukimon's almost exactly the same as Myotismon, but he just removed the grimness and replaced it with diaphragm bass. And Falcomon... have to say, I didn't expect a British ninja. To me, it kind of robs the feeling that he and Keenan grew up together if he sounds like a grown-up already. It also makes me fear Peckmon and Ravemon's voices even more. I swear, if Blum doesn't bring at least some of his Yamaki/Spike/Mugen flavor to Ravemon, I'll declare Data Squad a waste of a translation.
But let me say this, Thorsten Laewe's RizeGreymon Digivolution theme remix is freakin' addictive. I've got to find an MP3 of that somewhere, it almost made the scene better than the Savers version (I say almost because Quinton Flynn bombed at making Marcus dramatic...)
