Plants vs. Zombies 2 has hit a wall-nut and won't launch on July 18 as intended. According to game's official Twitter account, the continuing battle between flora and undead won't continue until "later in the summer."
In follow-up tweets, PopCap notes the game will still launch on "Apple products first," as it was originally announced and scheduled for iOS. After that, more braaaaains will be found on other platforms. It is the PopCap (and EA) way.
