Any clue when they will release the new version of the code?

Nope.  But normally there are monthly cycles for patches so 9.1.1.4 should be out by end of this week I expect.  As for 9.2.0.2 or whatever it will be called - no idea.  It all depends on how much there is to fix for things found to be broken.

As per one of the existing threads here, it has been pulled out due to some issue discovered.  Normally initial releases are found at https://support.emc.com/downloads/1095_NetWorker and post patches at ftp.  As always, I would recommend to wait for at least some patches to be available unless this is pure test/curiosity...

Indeed, 9.2.0.3 is now available for download.
