I'm not sure it's good news satoshidice doesn't belong to the real economy. I'd rather wait for news from a dealer who would sell cars in BTC only. Still, it's an astonishing achievement. You could have bought several superb houses and many cars for that kind of money!
This, I wouldn't pay even half the amount for a business which could potentially crash tomorrow, or even worse, get wrecked by Gavin and other 3rd parties.
