Of importance to IS owners (though it's unknown if these items will make it into the 2005 IS3X0), are Bluetooth and XM satellite radio. Lexus has announced the availability of the two technologies in select models. The LS will of course get everything, it's BT and XM that will really need to make it to the IS. We're already at a disadvantage in power to most of the competition and now we're falling way behind in features (witness the impressive new Acura TL).
