I have always left mine on auto on my previous cars and they all were still perfect after 300,000 miles. Can't find a single official statement on the subject.

Why do you think they're so many OEM branded fakes being sold on places like Ebay. Unsuspecting customers in the masses and it mostly cheap junk posing like Philips, Osram, Bosch... etc |
It has to do with the salts in the bulbs. If not given ~5 minutes of on time to fully heat up, the salts will deposit oddly and effectively be "lost" as they won't turn into a gas again. There is also the issue of the electrodes wearing, which happens on start up.
Also keep in mind, HID bulbs aren't like halogens. Halogens will keep something like 95% of their output right until they fail. HID's will taper off and color shift well before they stop working. (Can't seem to find the graph I had of this, but it's pretty comical how much light is lost)
I know of people that change their HID bulbs yearly because of this loss of light. There's a hell of a lot of early HID cars on the road today that are outputting less light than a cheap halogen and at colors that are difficult to see.
