I was reading impressions from people on some other forum and they seem to prefer Red Alert 3 to C&C 3. They say that in RA3 you have to build different units to win. In comparison in C&C 3 if you were Nod you just built lots of 'helicopters' (forgot their name), bought update that installed laser guns onto them, maybe built some tanks and you won the battle. If you played GDI you just produced massive amount of mammoth tanks and you won (at least in single player it worked that way, not sure for multiplayer). Here (in RA3) you have units that are specialized for killing certain enemy units (like only soldiers, only air units, only naval units, etc.) and as far as I know there is no 'general killing machine' like mammoth tank in C&C 3 or Overlord tank in Generals.
In RA3 the building system is different from side to side. Allies have the 'normal' building system. You click the building you want to build and after some time you just place it onto the battlefield (you need to place it into range from your other structures (like in RA1 and RA2)).
Soviets have Age of Empires system. You click the building you want, you place it onto the battlefield and it starts building. While it's building it is vulnerable to enemy attacks and you also need to place it into range from your other structures (like in RA1 and RA2).
Japan has some sort of Generals style system. You build a robot which you then send (by land) to any part of the map and transform it into a structure. The robot has weak armour and it can't defend it self.
As far as I know there are no space ships (Yuri style), but there are some strange flying objects. Many units can transform from naval to land unit or from land to air unit and also the opposite way. Only Japan has a unit that can transform from air to naval unit (and if IIRC it can't transform back).
Units are wicked, strange or whatever you want to call them, but they have been like that already in Red Alert 2 (shooting dolphins, mind control tanks, flying saucers, giant squids, etc.). I just hope that the game will be well balanced and that the gameplay will be as good as they are promising (that you will have to build naval and land units in order to win (mostly because now almost all structures can be placed into/onto water)).
Oh, and the final thing that I'm happy about: walls are back!!!
