This confirmation comes via a couple of brief statements made at the conference by Hiraoka Toshiyuki (平岡利介), the General Manager of TV Tokyo's Anime Business Division.
HIRAOKA Toshiyuki - Anime Business Division General Manager said:「今後が注目されていますが、サトシの冒険はまだまだ続きます」
"What will happen from now on is attracting attention, but Satoshi's adventures will continue."
"As to what these adventures will go, we will release information in a future anime broadcast."
President Ishihara meanwhile made several comments about the worldwide reaction to Ash's Masters Eight victory.
ISHIHARA Ichiro - CEO and President said:「アニメのキャラクターへのお祝いのことばというのは初めてですが…」
"It's the first time I've ever congratulated an anime character"
"My grandchildren love Pokémon too, and sometimes cry and get angry with me when there's no broadcast"
"About Satoshi becoming the Champion, I heard people around the world had sent their congratulations. We've been continuing to broadcast Pokémon for a very long time, so we're extremely happy this has happened, and want to congratulate Satoshi as well."
At this stage, no explicit statement has been made about what form this continuation might take, which has led to concerns being raised by some long time members of the Pokémon anime fandom.
President Ishihara's quote regarding his grandchildren's feelings when there's no broadcast does at least give us some hope that Pokémon will continue as a weekly anime series. We should hopefully have more information once the next episode of Pokémon airs in Japan tomorrow, December 2nd.
