I don't understand why people think this hobgoblin is too much like an orc. I think they're really a great contrast to orcs--orcs are savage and bestial barbarians, hobgoblins are buttoned-up, intelligent soldiers. Orcs are a threat because they are strong and brutal, hobgoblins are a threat because they are organized and strategic.
I think the breakthrough of the hobgoblin Jon showed is that it's less monstrous (orc-like) and more human like. In 3e art I couldn't tell the difference between orcs and hobgobs, but this concept looks exactly like a hobgoblin.
