Rumors and FCC documents suggest that the N900 will be available in USA with T-Mobile's 3G frequencies. Nokia probably wouldn't go through the effort of building a special version for T-Mobile US unless they have a deal in place that the device will be subsidised by the carrier.
So there's a fair chance that this will be available in the US for considerably less than 500 euros (my guess for the T-M price would be $199, but who knows?).
