Gossip. Gossip. We Want Gossip....
** Rumor **: One user reports calling SWK to check on status of POS Professional. I believe this was originally slated for July 15, 2012 release.
Sounds as if the release will be delayed (at the minimum) and may be stretched further to v5.0 and require some amount of re-write. SWK is supposed to be providing further guidance later next week.
