There are a few people currently saying this could be an act of misdirection by Disney and Lucasfilm and that the series has been cancelled, but only on Cartoon Network. Disney might decide to transplant the series to Disney XD to bolster its schedule and ratings there (which aren't terribly high as many, many American households don't get XD as part of their cable or satellite packages).
Jedinews has a history of posting generally accurate information, though, and they helped break new developments in the past. Were it from some basement blog or no-name website without a good track record with the fans I wouldn't give the story much if any heed. They're one of the biggest and most succesful SW fan and collector sites in Europe.
We'll see. But the current consensus seems to be that some sort of axe has indeed fallen on the series.
