The Cyan thing happened because some users installed the preview software onto their enterprise-encrypted devices - to my mind, this is a pretty foolhardy thing to do as you don't know how corporate EAS/policy will interact with preview software.
The problem is that Microsoft update servers don't know whether each phone is encrypted, so the only way to prevent bricked devices is to halt the update for everyone until it can be corrected - obviously, this hasn't been an easy fix. There's been a pilot fix deployed for some handsets for some carriers/regions. I had word yesterday that the DfP Cyan update will be resumes "shortly", although I don't have any more definite timescales than that.
As mentioned above, the Cyan firmware isn't a huge update, and won't do much to improve your life with your phone (Nokia push it so hard because they bundle firmware updates with major OS updates).
Developers aren't being left behind, we already have GDR1 after all, and GDR2 is on the way sometime soon.
