Eraser, that's my hope as well: not worrying about microing workers should free up players to focus on the fun part of an RTS game: using your units. Positioning, micro, activated abilities, map control.
But, despite the relative paucity of gameplay footage, there's been a lot of concern about how this game is going to be played. In addition, it could be really useful for pro players to see high-level gameplay, to get them excited, or at least thinking about, End of Nations.
Again, I'm not a pro. I'm just suggesting a piece of marketing that could work to assuage the fears of the common gamer and potentially interest some more pros in the game.
