Olympus Pen firmware update - vapourware??

Hi

Back in mid-September, dpreview and other sites reported the release of a firmware update for the Olympus E-P1, improving the auto-focus responsiveness in particular.

See http://www.dpreview.com/news/0909/09091501olyep1firmware.asp

Has anybody been able to download & test this update?

I haven't been able to find it on the Olympus support sits in either UK, US or Japan - is it vapourware??!

Thanks,
Richard.
