First day of the ACUC, Jon Bertman said "it is on the schedule to release the beta in December. We hope to have it then".
Last day he said "we WILL have it by January 1, 2011."
Remember that Jon's betas are usually fairly stable and long, V5 just came out of beta in April I think.
Also probable Version 5.1 with a lot of e-prescribing improvements and other fixes possibly by the end of July.
More to follow in Version 5.2 but date was fuzzy.
