I have no inside knowledge on this topic, but Microsoft has publically stated that as long as there is a market for on-premises Exchange, they will continue to deliver it.
For large companies Office 365 is more expensive than on-premises solutions. I haven't figured the break-even point recently, but the last time I looked it was about 20 months for 2000 users. But the real kicker is that not many features are going into on-premises software like Exchange and Office. It's not "cloud first" anymore (if it ever truly was), it's "cloud only".

Office 365 will be all that's left ... Updates won't matter then.
