There are no official change logs or update schedule, but various reports confirm the availability of these updates on all three devices. If you own one of these smartphones, it's a good idea to check for updates.
By the way, if you have a BlackBerry Priv from Verizon, the carrier has recently begun seeding the long-awaited Marshmallow update, so you should probably get that first, if you haven't already.
Anyway, if any official statement comes up, we'll make sure to keep you updated.
I think your opinions are stupid :D
And I know you're wrong. :D
They get updates every month - it's nothing new. If it had been a different OEM there would be a street barbeque and an army parade and fireworks because it doesn't happen so often.
