Looks like it will be awhile till prices come down on G3, "120 GB and 250 GB, priced at around US $366 and $767, respectively."
As far as I know those are the US dollar equivalents of the price a UK retailer has listed as a preorder or something. The US pricing is supposed to be $280 for the 120 gig drive, and $580 for the 250 gig drive. Street prices of course are probably going to be higher than that for a while unless intel can flood the market with them. They're on the 34nm NAND too as john mentioned, so I'm happy they're priced where they are. All that remains is to see if the real world performance is worth the premium.
