I'd been waiting anxiously for the last few weeks since the Spurgeon Commentary: Song of Solomon and Jonah prepub was FINALLY showing as shipping today (it's been listed as prepub for ELEVEN YEARS). Even this morning it said it was going to ship today. Then, without notification, the date has been pulled on it and it's back to "in progress".
I thought that Logos said they were updating their processes so that erroneous ship dates were no longer going to be added to prepubs to get our hopes up, but it appears that has not been the case unfortunately.
