Another question and answer post has been made of the official forums. This one is just some general infomation on C&C4, which includes the mention of the game only shipping with about 12 maps.

• How long does it take for each Super Weapon to charge?
  Each superweapon takes a total of 4 minutes to charge to maximum power. However, after only 40 seconds, you can fire off a weaker version of the superweapon. The GDI Ion Cannon has a total of 6 charge levels, with it taking 40 seconds for each level. So, the longer you wait to fire your superweapon, the stronger it gets, until it reaches maximum strength after 4 minutes.
  
  
• Is there a limit to how many Commandos can be on the field at once per player?
  Each player has a limit of a single commando, just as in previous games.
  
  
• Can a defense player select multiple structures at once to target a single enemy unit?
  Yes, C&C 4 now allows you to band box select multiple defensive turrets to give orders to all of them at once. You can also select multiple structures through shift click, and any of the other multi-selection mechanisms in C&C 4. However, defensive turrets are not included on the various unit selection hotkeys, so you won’t have to worry about accidentally selecting your structures.
  
  
• Will the Defense Class be able to power down their own structures?
  The defense class does not have a way to individually power down their structures. However, if the defense crawler is destroyed, or dismantled, their structures will lose power until they deploy again. Also, if a player changes classes, their remaining defensive structures will stay on the field, but they will be unpowered unless the player switches back to the defense class.
  
  
• Around how many maps will be playable in Skirmish?
  There are a total of a dozen multiplayer and skirmish maps, set in all of the various regions in C&C 4: Polynesia, PanAmerica, Arctic, and Junktown.
