Eh there might be. I think they still want the OG look mostly but will add a little something else to it. At least from leaks I seen for 2, maybe 3 of the villains if they hold true and Electro already has yellow lightning as opposed to ASM2 blue lightning.I know everyone is excited to see their childhood villains again...
But personally, I would have preferred new designs and actors for these classic villains -- Goblin and Doc.
