In 2009, new material was shot for the fourteenth season of Barney & Friends (Which featured rearranged sets of the twelve-minute "half episodes" from the tenth and eleventh seasons - Two per episode, as they were presented originally), as well as for six "clip show" DVDs. (Let's Play Outside, A-Counting We Will Go, I Can Do It, Big World Adventure, A Very Merry Christmas and I Love My Friends)
The studio in which Barney was shot was closed down sometime after this, so the set no longer stands. In addition, many props were sold. For the time being, there is no replacement set.
All of the 2009 material has been released (As far as I know), and every Barney release since has been a compliation of episodes from the latter half of Barney & Friends.
From what I know, some material was shot in 2010 (At least for
A Very Merry Christmas and
I Love My Friends, but I think most of the other clip shows were filmed that same year) until rehersals started for
Barney Live in Concert - Birthday Bash. The sale I believe occured in September 2011 (one of the actresses on
Barney notified a friend of mine (who happened to be friends with this actress) of this months after it happened and I was notified by him). Basically, since then, the cast and crew of
Barney & Friends know as much as we die-hard fans do: nada, zip, zilch, etc.
On the subject of DVD releases, I still don't get the logic behind ignoring the earlier 10 years of
Barney's history, save for the aging quality of early
Barney & The Backyard Gang titles (two of them used blue screen and look horrible by today's standards). Hopefully, something will come out for the anniversary. Heck, even current Barney fans (fans in the target age range) are watching the old shows as well as the new ones.
