Legends of the Dark Crystal, Vol. 3 Cancelled?

So, according to Wikipedia (not always a reputable source for information), has stated that while Vol. 2 is to be released in August, LOTDC's third volume has been canceled. Can anyone confirm this? Further more, if this is true, does it bode ill for the franchise (proposed TV series, sequel, etc)?

Some time ago, I've actually asked Heidi Arnold (the artists of both volumes) via her dA account, about the info regarding the number of volumes. Here's what she said:

And to prove that this is not a hoax, here's the link to the comment:

Hope this helps.
