We can say "full refund" but it won't be true, since the only scenario in which we'll miss July date (not August, July was already sold out) on SP30 is a total catastrophic one, in which refund policy won't matter.

Unlike other vendors, when we're committing to a date, we mean it.

As explained before in the thread, the SP30 ASIC (RockerBox) is a die shrink (40nm -> 28nm) of our SP10 ASIC (Hammer).
It's a relative trivial project, this is why we're feeling safe to do pre-orders for SP30.

(unlike our 3rd gen ASIC, PickAxe for which we won't take pre-orders since the ASIC is an higher risk)

Needless to say, even in this relative trivial project we're doing verification + FPGA validation.

The exact status of the project:
We've submitted final net list to Global Unichip, the tapeout will be in the beginning of May.

Edit: ASICs in the beginning of July. In Hammer case, we had working SP10 system within a week from getting the ASICs.
