Vega 56 orders have just gone up. Anyone who's in Europe and interested in one should check Scan.co.uk, who have them for £379, which at the current £/ exchange rate is about 410, which is likely the cheapest you'll see it at for a while (of course you have to put up with the stock cooler, though). Stock probably won't last long, though.
Edit: Overclockers.co.uk have them for the same price of £379, for anyone looking.
