The official release date has been announced on Pokémon Sunday: September 18, 2010. Additional clips from the games were revealed.

Also, for anyone who`s wondering, right before the Pokemon Black and White footage was shown, the narrator said "Pocket Monster.....kakusei", which means
"Pokemon.....awaken", or "Pokemon.....the awakening", depending on one interprets "kakusei". (Note that "Pokemon" is short for "Pocket Monster")

Nothing really suprises me about todays pokemon sunday.

THe love how the trailer stops in the middle!

I noticed the person opening his eyes was followed by an evil looking person wearing the same uniform. I'm guessing those 2 are from Team Plasma. The second guy was probably and admin or the boss. The person with green hair talking in a cutscene near 0:53 is standing in front of a ferris wheel. A major cutscene will take place at the carnival The green haired guy also says "pokuha chyanpiono koeru." From my limited understanding of Japanese, it kind out sounds like Pokemon Champion come (command). Koeru means come right? Correct me if I'm wrong. These are just mere observations based on information I have gathered and must be taken with a grain of salt just like any other predictions.

Whoops I misread. It says bokuha chyampiono koeru not pokuha. In that case, the meaning changes to I will come/become the champion or something along the lines of that.

Heh, so we're getting a totally new game only 6 months after a remake? That wins.

This is only the Japanese release date, right? Geesh, we have to wait half a year to get them in English.

That's great. We'll be able to get more videos/pictures of the games when they come out in Japan.
