Captain Underpants and the Plot of the Wicked Wikipedia

This may change in a day, Wikipedia being what it is, but as of this moment right now there are two mysterious entries on the subject of Captain Underpants (look under Series of titles), detailing upcoming books that are (according to Scholastic) not currently in the works. Is this the frenzied scribblings of an uber-fan or could Pilkey be mucking with our brains? Only time will tell.
