waazzupppp,
I know what you posted about support thru July 2014 once was true, but they've changed it since then...copied straight from Microsoft's support pages...
Products Released Lifecycle Start Date Mainstream Support End Date Extended Support End Date Service Pack Support End Date Notes
Windows Phone 8 12/14/2012 1/12/2016 Review Note Microsoft will make updates available for the Operating System, including security updates, for a period of
36 months after the lifecycle start date. These updates will be incremental, with each update built on the update that preceded it. The distribution of these incremental updates may be controlled by the mobile operator or the phone manufacturer from which you purchased your phone, and installation will require that your phone have any prior updates. Update availability will also vary by country, region, and hardware capabilities.
Microsoft Product Lifecycle Search
Looks like basic OS updates through Dec of 2015.
I know these are never set in stone and although we may never see Black, I bet at least people with developer preview will see 8.1 soon.
