A feature, with a broken link, on the Arrow website hints that the Diamond Dragon will be for sale Q1 2008.
The dragon features a 175C operating temp tolerant junction and power levels of 5 to 8 watts. It's supposedly the same size as the Golden and Platinum dragons but with a bigger chip.
The only press I can find about it is from Nov of last year

Their "typical" top bin cool white diamond will produce 250lm at 1.4a.
