I rarely check this thread even though I was the one that started it.

To update the general readers:

1. All people who bought VCU1525 cards right when this thread was announced, have already ROI'd their cards (mostly from mining 0xBitcoin at $15/day for 6 months before BCU's shipped, and then Microbitcoin at $20/day for a shorter period); unfortunately by the time BCU1525's shipped, other FPGA farms were online and profits were less, so no, BCU1525 have not come close to ROI, even though early VCU1525 already paid themselves back

2. I am still working hard on X16R/RT/S for BCU1525 and CVP-13, being released in the next few months

At $2 - $2.5K per BCU, personally I would buy every single one if I had money, I already bought some second hand ones (as many as I could afford).

This is not in any way a suggestion that you should get into FPGA mining.  However if you already have hardware, some pretty good bitstreams are around the corner.  Having said that, I would wait until the new bitstreams are actually available if I were you; it is always better to buy hardware that can already do what you want, rather than 'might' do what you want.  In my case it is different, I can buy 2nd hard hardware safely even before the bitstreams are available because I'm developing the bitstreams and I know they will work, but outsiders don't have that certainty and should play it safe.
