This comes from the official Meerkat Manor fan website http://www.meerkatmanor.co.uk/the-burning-question.htm
They will not make a decision on Season 5 until Season 4 airs in Europe. That doesnt begin until February 2009. So we are looking at May or June 2009 to even find out if there will be a Season 5.
According to this Season 4 was a huge success in the USA. The film crew is not going to return to the KMP yet, but sometime next year after MM airs in Europe. A reminder: MM normally airs every night for two weeks in certain countries (including the UK). The film crew normally goes in September/October.
Just hope the crews dont miss all of the antics going on. You cant write a script better than what we see going on right now. Can it get more interesting that this???
