It looks like a slew of high definition games could be bound for the iPad including Plants Vs Zombies HD, Flight Control HD and Worms HD.
The listings for the not-yet-available games were uncovered by the folks at Pad Gadget while they were digging through the web version of the iTunes preview.
While there's no way to tell if these are all games bound for the HD iPad, it makes sense. None of the games come up when you click on them, instead delivering a message saying they're not yet available in the US.
Here are all of the HD games found so far on the pages.
