You can rest assured that there will be further OS updates to the Rev2 to fix known bugs, etc. Bear in mind that version 1.1.0.3 was release at the very end of January--that's not very long ago.
When new beta versions are stable and potential release candidates, they are first made available to the public in BETA state here on the forum.
As a general rule though, we do not comment publicly on what aspects of the OS we are working on when we do maintenance, or provide specifics on when releases can be expected. When new versions are available, corrections and additions are marked in the changelog in the dedicated OS updates thread.
