The Optoma PK102 is launched in Japan

Optoma are now selling their new PK-102 pico projector in Japan. The PK-102 has the same projector engine as the PK-101 (DLP, 480x320), but it has 4GB of memory and can play MP3 files and has a built-in speaker. It weights 118 grams.

It can be bought in the US as well, through Amazon, but it is very expensive, at 650$.
