I guess the delay is with BFL/Avalon. But those aren't expected until at least 6-12 months. At that point, pyramining may be great. But at this point, trying to get people to invest is screwed up. I could spare the couple BTC I had. For others it may have taken them months to mine or paid $200 for.
The delay has nothing to do with BFL or Avalon. Pyramining is building his own ASIC and that takes time (as the others mentioned have demonstrated). Current projections are for deployment next month!
