It's not multi-player ready until items, stacked unit combat mechanics, individual unit mechanics and a host of costs/trade-offs are addressed.
Once some or most of those are addressed, they can do MP and get down into the real nitty gritty of player vs. player balance. I feel like the game is currently totally balanced against playing the AI, and not against playing a person. MP balance is one of those things that goes on forever, and ever, so it would be a good idea to have solid fundamentals to work from before they wade into that.
