Hmm... That reminds me...
Since Cartoon Network's part of Time Warner, and Warner Bros. is also part of Time Warner, and worse, Kids WB! also part of Time Warner, and if Time Warner is merging w/ CBS, and KidsWB! w/ UPN... yeah...
You're right, rumor-goers... Well, partly right...
Pokemon will have a tough time finding a new TV home in the USA, but it won't have as much a difficult time in the European world(where the "brand chemistry" is different than the US's "brand chemistry"... Remember that some games in Japan can't even make it Stateside because of "corporate conflicts") , or the US DVD world in that matter, and if this is true, then Pokemon will be "semi-cancelled" in the US after the "Secret of the Mirage Pokemon" special, but in Europe, and on DVD in the USA, Pokemon will still air, but given the attitudes in the Middle East, yeah, it will find a difficult time in finding a good spot in which re-runs on DVD will not be the only things that airs, as the spot that it finds will also air all-new episodes...
Here's the source I found explaining this info.:
