My guess is 06/11/2009

Don't forget we already held a contest back in April to predict the announcement and release dates. Here were the predictions:

neatojones: announced May 11, released Jul 3
chlettn: announced Sep 2, released Sep 2
FRZ: announced Aug 12, released Nov 16
eiffel: announced May 30, released Sep 8
quipper8: announced Sep 15, released Oct 15
VDVsx: announced Sep 2, released Nov 15
lemmyslender: announced Jun 30, released Sep 30
debernardis: announced Jun 2, released Oct 10
sachin007: announced May 15, released Jul 25
penguinbait: announced Jul 6, released Sep 1
qole: announced a few days before Jun 21, released Jun 21
TenSpeed: announced Apr 22, released Jun 4

It looks like only FRZ and VDVsx from that list are still in the running.

Roger
