I guess it was to cash in on the fact of 5D starting and wanting to move onto newer stuff. There may be a chance of the last episodes getting dubbed if they go back and do a "Lost Episodes" set of the final GX episodes saying "The Conclusion of Duelist Academy is finally here" or something like that. Sort of like how FUNi did lost episodes of GT except this time it's the end that needs to be shown, not the beginning.

...... The same talkbacks you saw me do last year but with new episodes.
