This new commercial from Japan for Pokemon Diamond and Pearl on the DS shows new Pokemon, along with customization, and other in-game gameplay like battles.
If you’re wondering what the Japanese voiceover from the commercial says, he mentions if you preorder Diamond, you’ll get the action figure off the cover Pokemon. Same with Pearl and its Pokemon. Preorder both and you’ll get another one, not yet revealed. I, personally, expect it to be this generations Jirachi.
Gary wanted to know if in the new DS Pokemon games they move during battles. If you look at these Pokemon battle videos from the official Pokemon page in Japan, then I’m sorry to say it looks like they still don’t move much, if at all.
