Are they planning to add "Single Player" or whatever of that sort at all? All I see when I hop into the game are "Custom Games" and "Versus", both of which are meant for online play. I am more of a single player Warcraft RTS player myself, and often do enjoy playing custom campaigns, single player RPG maps and what not.
From what I can see here, they intend us to have internet connection at all times and we are screwed otherwise. I recall Warcraft III being a good time killer when internet runs out or something unexpected happens, there was always something to do. If this remains in current state, apparently I'll be forced to eat my nails until internet comes back on and not count on this game any more in such cases.
