7.5 Beta or 7.019 patch?

I am new to the upgrade process. Currently we have the latest production release of ServiceDesk. Since we have MSSQL as the back end db, we are suffering in regards to certain functionality (Auditing, Surveys), as well as regular functionality (memory leaks, sso sign in issues), and new features for the 7.5 release (customized forms).

My question is...will there be a 7.019 patch released separately from ServiceDesk 7.5? If so, when is it scheduled to come out, and what does it fix?

If we are required to go to the 7.5 release....when is it due to come out? I have seen the blogs, and the updates, but there has not been any updates to this product all summer. The product was slated to be released in June/July...and now we are almost in September. I signed up for the beta, but I am hesitant on putting beta software in place for our production environment. Will the beta be stable enough to do this? If the beta is not meant to be put into production, when are we looking at the finalized 7.5 product to be released...November/December, or further into 2009?

Thanks,
Dave
