1Up reporter Kevin Gifford interviewed Pokémon Company head Tsunekazu Ishihara in late August and discussed the current outlook for the Pokémon Company. Tsunekazu Ishihara said there are a bunch of surprises in store for the second half of 2011. Below is the quote from the interview.

"To be honest, there isn't much I can tell you yet, sadly," he said. "However, I can tell you that we've got just as many surprises in store for the second half of 2011 as we had for the first half, so keep an eye out for us. I don't think every Nintendo DS use has immediately upgraded to the 3DS, so while we'd like to keep DS gamers close in our minds, we also want to show people how much the world of Pokémon can be expanded with the 3DS's feature set."

im sure 1 of the surprises will be a new game or games of course if thats the case then it will get fun

Hum, I'm still wondering how to interpret that last sentence... in term of surprises, maybe it'll be a 3DS Virtual Console release of the original Pokémon games? But he also mentions DS-users who haven't upgraded yet... so maybe they'll announce the 3rd 5th Gen. game, thouhg still on DS? A game that would be released on DS, but with 3DS-exclusive features? I shall not get my hopes too high, though.

Anyway, I'm really looking forward to their announcements, later this year.
