One word : FAPTASTIC~!
Damn, the forefront tease on the seiyuu voice-acting is damn good. Konishi's vocals on that last part there made me tremble in school~girlish excitement and Koyama's serious-adult-no-nonsense Zepelli tone sounded really pleasing to the ears. Hikaru's voice as Dio was pretty good as well, though it did sound more rough and gritty than I thought it would be. It felt more like a RAW Seto Kaiba more than anything.
And the visuals. DAMN!! If the trailer is anything to go by, it's almost like a genuinely faithful early ARAKI adaption, though it does evoke some feel of Raoh-Gaiden~ish feel with the thick lines and gray-toned rich non-digital-like colours. I don't think it will have the same EPIC background colours/tones/effects of Raoh Gaiden though.
