Ok BB10 is not quite dead yet... but the end is coming and it's probably not far off.
BB10 has been moved to a palliative care hospice. (No new SDKs / APIs / developer tools.)
There is a Do Not Resuscitate order on file. (No more significant internal development / most of the developers laid off.)
The nurses are keeping it comfortable and checking in on it now and then. (We're fully committed! Two security updates coming!)
BB10's friends and loved ones continue to see it every day and put on a brave face.
