Wow, so much information in this weeks blog, where to start lol. The new characters both look amazing and yep I agree with you about Orcs being typically stereotypical, regardless of which game/book they appear in, so it's great to hear you say how you have plans to expand on their normal tropes.
Interesting that the human character is a "special character" I can't wait to see what that actually boils down to in the actual game and nah I don't think these behind the scenes snippets ruin anything for anyone. There's no harm in showing pictures of characters, you can't tell just from a picture what their personalities are going to be like or anything about the storyline they will be featuring in, if anything by featuring them in BTS articles it just means players are more likely to keep any eye out for them in the game.
Personally I would like to see five parts to Elven Kingdom, that seems to be a nice solid number to work towards.........although six episodes is an even nicer, round number and what most UK sit-com TV series tend to contain nowdays ;)
Oh and did somebody say VOICE ACTING!!!!!!
