I don't have dates yet, but it's important to consider that most HID systems have a self leveling system. As if the HIDs aren't already expensive, this adds complication and cost if you wish to do such an install correctly.<P>None of us have seen the Volvo system, but I know that single Xenon equivalents from companies like Volkswagen and Audi go for over $1000 typically for the assemblies. It won't be cheap if they do offer a kit. Even if they don't though, I'm sure someone will eventually post all the parts necessary for the upgrade in an FAQ.
