I thought there would have to be a breakthrough to get that sort of power into one processor.[/QUOTE]

Well, the breakthrough is a huge hall full of PROCESSOR.If you want to see it, look for IBM Blue.The US Army used it to simulate nuclear weapons explosions so its quite good.

The real potential is that this kind of game won´t be sold on cd or dvd or any other media but rather played online against a central computer somewhere. So you can sign up for a game against hundreds of other players online.[/QUOTE]

How do you download it?
Then it would be impossible because other players won´t be waiting til you finish your turn, and if the battles are going to be similar to MTW or RTW, you can just play RTW multyplayer, its much easier.
BTW, 3 DVDs its about 25 GB of HD space, suppose its compressed, you will probably face some 50 gb of HD only for the game...I think its not THAT much...

Do you realize that were talking as if were about to make it ourselves?
...Who knows? Mybe we will...
