I emailed my contact at Pentax who expressed surprise. I was told they were contacting the web team for an explanation.
If you look at the page it simply says the domain name has expired and is pending renewal. Somebody messed up, but I seriously doubt the gallery is going away. If you want to close a website you take the site offline, you don't just wait until the domain name expires. Even if RIcoh is closing out the PPG they would not want anyone else to get that domain name.

Quite possible the registered notification emails are no longer valid. A screw up but if the notices went to ex-employees or abandoned accounts easy to see how it slipped through. When I took over my present job I nearly lost our domain name because my predecessor had passed away and the notices were going to his personal email.
