Maxis has revealed what SimCity players can expect out of the upcoming 3.0 patch. A majority of the update will focus on the road system, such as traffic, transit, vehicles, and so on. Air pollution, trading, and data layer issues will be addressed in the fix as well.
Update 3.0 will also be adding some content, in this case an increase in hotel models to add more hotel variety for players.
You can see the full patch note over on EA's forums. Now the question is, will these updates actually fix the problems this time around?
