If it seems as though Popcap Games marvelous cute and inventive take on the tower defense genre, Plants vs. Zombies, has been in the works for the iPhone/iPod touch for a long, long time, it has – the game was first announced in last August. Although Popcap Games didn’t make its “late 2009″ window, I can forgive the kindly team of casual gaming gurus because the trailer for the upcoming Apple port looks really, really good (and they know how to thoroughly rock a Halloween parade).

Judging by Popcap Games’ video, the winning gameplay looks in tact, but I wonder how the multi-touch will be implemented (which has, unfortunately, added a cumbersome elements to many good iPhone/iPod touch titles). Still, the prospect of playing Plants vs. Zombies on the Apple iPad’s slick 9.7-inch display sounds quite delicious, especially on long flights or road trips, if you happen to think the tweener device is worthy the dough.
