Is there going to be a jackass number 4?

there will be the release of Jackass 3.5, which includes everything that didn't make it into Jackass 3D. It should include stunts such as, "Party boy" and "Keep God out of 3D"

As far as the 4th installment, I think Ryan Dunn's death my have great impact on that decision for them, but rumor has it that a 4th installment of Jackass is in the works.

Currently under the beta name: Bad Grandpa

The plot is, get made up into 80+ year old men (as they have in the past) and make a full length feature filmn on this single premise.

Some of the original group are not into this idea at all and have said that they will not be in it if this is the case.

I have a feeling if this film does see the light of day it will quite possibly be their first box office flop.
