Please reconsider the release of Dolphin 10 to a later date. Many have yet to fully test modules with Dolphin 7.3. Many have yet to work out bugs with the upgrade patches to 7.2.1/7.3; two members on Boonex has seen database tables related to versioning and licensing disappear during an upgrade; one was me and I do know how to upgrade. It is too early to release an entirely new Dolphin version.
