It's finally coming to us!!
Well, nobody is 100 % sure, but it's most likely that that's what EA is announcing on the 6th of March now. Also, here's a link to a thread about this subject: http://www.neogaf.com/forum/showthread.php?p=35585202
The rumors have gone off everywhere, I've seen the same thing on simtropolis as well. A friend of mine and I are already discussing how we're going to build our cities in the multiplayer of Simcity V and maybe make a big journal out of it!
