All Insiders running Windows 10 with their Registered Microsoft Account will get upgraded to the final release build of Windows 10 starting on July 29. If I am reading right, we won't be able to delay this upgrade. And why would we? :) We can just consider it a part of the Insider Program.
However, we are allowed to delay upgrading to Windows 10 from Windows 7 and 8.1 for up to one year after final release. That is one of the few concrete facts in this whole Technical Preview.
