This is for people who just need to have that "official" stamp on everything related to their console.
Sony Japan has started up a PS3 hard drive upgrade program. Owners of pretty much any current PS3 model -- even 20 gigabyte launch units -- can send in their system to have their internal hard drive replaced with a 250 gigabyte disk.
No, this isn't a free process. Not even close. For the parts and labor, Sony is asking 18,000 yen. That's close to the price of a new PSP-3000.
It looks like Sony takes care of everything for you, though, from swapping out the drives to moving all your data over from the old drive to the new one. They'll even back your old hard drive.
Still, it should be noted that you can easily swap out hard drives on your own or opt for an external USB solution, both at far less cost. This is something that Sony's upgrade info page fails to mention, unfortunately.
This program is only available in Japan at present.
I ask you, would you really pay old Sony to upgrade your PS3's hard drive? I sure as hell wouldn't. Leave feedback via comments.
