Is it actually worth investing considering that if I pre-order it now I will have it by June? (according to butterfly labs office)
Nobody can tell you whether or not it will be profitable to pre-order an ASIC as nobody can know for sure, but I will say one thing, BFL originally said the release date for the ASIC's was October 2012, and due to delays it keeps getting pushed back, so there is a high probability you won't get it in June if you order one.
Has anyone called any investigators on them, i.e. the police? Seems logical considering how fraudulent they appear.
