I do not mind not knowing when 6.0 is actually released until it is released. I kind of like the excitement of waiting, hoping and wishing for how good the new AI will be.
Having testet out several combos of AI and looking through scripts, I am really excited about what seems to be Blizzards goals with the AI scrips, and what observer mode seems to tell about Starcraft II and its ambitions.
AI is very much so based on actions per minute, and as observer you can stay alert on what is going on in the game. Who is very active atm with the most APM? Who has the highest income? Who has the most units? Who lost the most and the least units? All these stats that usually could not be seen before the game was finished (and in our case, we can only see these stats with observer mode).
Also with APM built into the AI, it seems they plan to make this AI really good compared to the ones in Starcraft and Warcraft 3. At least that is my hope. Imagine if the AI would play like semi pro players at its highest settings? And if it doesnt then it should be possible to mod a good AI.
I have been thinking of ways to make the best possible AI scripts, and I imagine the best way to make them is to the script directly into the map, and then also adding ambush points and other pathway points to the map. Routes and such, that the AIs could use and make it possible to attack from several sides, or make siege tank drops in very tactical places. But that is just my dreams about where AI in this game could be going.
