Its already out on iOS.
Played it and its a piece of shit. Some of the best plants from the old game like Stompy, Fire Wood, Frost Peashooter has become IAP, while the game is actually quite difficult to play now because EA wants to encourage you to do some IAP. Progression of the game is blocked by gates now, where you need to collect randomly dropped keys to advance in the "story" or get new plants.
Havent seen the old break the vase mode, Walnut bowling and so on yet. Zen garden is gone too. To encourage you to spend money, they made some of the old zombies like the bucket one to be very very tough to kill, probably as hard as Gargantuan in the first game.However, some of the new zombies are quite interesting to fight with, while consistent to the theme.
There isnt enough levels so far, so they force you to play the whole act again once you reach the game to the next so that you can collect those stars to unlock the door to the next part of the story.
Crazy Dave isnt as funny anymore, while the new character felt kinda soulless with no pun intended.
The game felt soulless where the charm of Popcap is gone. PvZ2 is polished, but it feels like it has no depth under its polished skin.
I say, just keep playing the old game. The new one is just awful. Still, its a soft launch, so thing will still change as you go.
Links? I can't find it so far.
