Same problem. I pre ordered with Dolphin Music and have been told I'm in the first shipment but I think they know as much as we do as all they say is that as soon as they get it they will ship it. One guy even said, after I had explained the release date on the Arturia website, "Well if thats the date they say then thats the date we will get them I suppose."
They dont seem to know very much.
I really would like a minibrute and I'm going to wait another two weeks but if I havent recieved one by then I'm just gunna get a Mopho and Tetra. Price isn't the issue here really. I do want the filter of the minibrute as well as the unique sounding brute factor, metalizer etc. However I have a feeling I would be better off waiting for a few to be sold on ebay and in the meantime just get somthing else.
