Wow, just saw this. Looks a lot like the wii tennis. I think it all depends on how intuitive the controls are. Looks great, will keep an eye on this game when it comes out.
Out now! Chop Chop Tennis has been approved. It's slowly showing up on the App Store now. Game on! ModEDIT... iTunes Link : http://itunes.apple.com/us/app/chop-chop-tennis/id368749678?mt=8 TA thread : http://forums.toucharcade.com/showthread.php?t=54006
