The date has been set.
I received an email from Sage announcing that the release date for SalesLogix v7.5.2 and SalesLogix Mobile v5.6 has been set - November 9, 2009. A bit about v7.5.2 from Sage:
"Sage SalesLogix v7.5.2 focuses on usability, quality and performance, partner adoption, and the customization experience. Activities and calendar enhancements, such as the ability to select and dismiss multiple reminders at once, streamline the user experience. Performance improvements target bandwidth issues and minimize latency. Improvements have been made to support multiple multi-byte languages in the areas of Unicode. Additionally, this release introduces a new developer community enabling members to exchange ideas and code samples-enhancing developer productivity. In tandem with this release, Sage SalesLogix Mobile v5.6 includes improved calendar integration, sData support, and usability improvements including BlackBerry Storm UI and navigation updates and support for high-resolution devices."
