Hey, so now Kamen Rider Dragon Knight won't be cancel according to this:
Adness Entertainment:
“On behalf of Kamen Rider Dragon Knight and
Adness Entertainment, I wanted to personally thank all the fans for the
tremendous outpouring of support we have received for the show.
Kamen Rider Dragon Knight is, as of now, scheduled to
air through December 26, 2009. The broadcaster has the option of taking a break
from the series to make way for any special programming they may have planned
for January 2010. We want to assure our fans that the channel is free to bring
back Kamen Rider and continue to air the series at any time.
After December 26th, the last two episodes of the
series will be available for online viewing on the 4Kids website.
Again, thank you for watching and for your support.”
So Kamen Rider Dragon Knight will resume after a short break around end of December and beginning of January. So that's great news after all! And if it won't be air on television, you still can watch the ending on 4Kids's website.
