Plants vs Zombies the Board Game

There's a strong trend for turning popular computer games into board games. There's a Starcraft board game, a World of Warcraft one (I own this one but it's so gargantuan and takes so long to play that it pretty much never comes off the shelf) a Doom one etc . . . even I'm putting together a board game from a computer game :)

But now, there's a Plants vs Zombies board game!

I haven't been able to get much information about the actual gameplay, but I love the idea of taking the rules of a simple computer game and translating them to a board game. How do you deal with going from realtime to turn based? How do you create a simple algorithm that can reflect a game's AI in a simple and easy to play way? I'm looking forward to seeing how they answer these questions in the Plants vs Zombies board game.
