The new series is coming to America on September 8th , 2006 at 8:00 PM EST!
Unlike the previous Pokemon TV shows this one will feature Pokemon themselves as the main characters. There will not be Ash, Brock or any of the regulars we have gotten used to. The Pokemon will not talk their usual way, they will be understandable!
Rather then hearing Squirtle say, "squirtle squirt squirt!" He'll say, "You dudes, wasup?" Or words to that affect.
To find more information about the show, and to see some screen shots I suggest you visit Serebeii.net
You can also check out The Cartoon Network TV Schedule to see what time it will be on in your time zone.
Bonus Link: For those who are unaware, Toys R Us stores will be giving you a chance to get Mew in your GBA games. How to Get Mew from Toys R Us is an article that reports on September 30th Toys R Us stores will be giving away the rare Pokemon and all you have to do is bring in your GBA and Ruby, Saphire, Emerald, Leaf Green or Fire Red.
