What about fight system? Will there be somewhat aimed blows (controlled by keyboard) or dodge/parry maneuvers to spice the fight up a little?

Hopefully not, at least not to a micro management extent. I don't like twitch based gameplay.

In the topic News from the front, Sektor said that in terms of click rate in combat, D2:ED should be better than DD (in terms of potential for repetitive strain type problems). That's about as much as has been revealed so far, though.
Various positions on combat systems were debated in the Wishlist topic, amongst other suggestions and related discussion.
