Very sad. Although the Jammin' Jungle Parade gets a lot of slack from the die-hard fans, to my knowledge it was still rated the highest (in terms of guest satisfaction) of all the parades on property.
It could also be argued that the parade kept guests in DAK until around 4:30 every day. With Avatar being Avatar, no new additions to DAK are being seen in the near future. TDO is essentially letting the park die, one step at a time.
