Will there be a Harold + Kumar 4

Neil Patrick Harris said in A Very Harold & Kumar Christmas that there will be a fourth one. I hope so but what can they do this time? A crossover with Cheech and Chong or Jay & Silent Bob? Time travel? Do you think they should make a fourth one or will it suck? I enjoyed AVH&KC but I thought it was the weakest in the series. I mean look what happened to the Austin Powers and Shrek films!
