Ok...I talked to IR for over half an hour..They basically told me the same as the other poster but I was told the delay is about the equipment used and exactly how it works.They said they were going to provide a "demonstration" of the process in the very near future to satisfy the FDA's concerns..Now with regard to P1 and 2..I was told if there was anything "material" we would hear about it and that the trial was going as expected..I took from that they (P1-2) are doing well,but this is only my opinion..I pressed hard to get more info and was told there are more N.R's in the pipeline and we should hear something soon.BTW she also said the quarterly updates in no way take the place of any n.rs they are going to be releasing.I spoke with a lady in IR and she was very polite...fwiw..
