I hope they show Sailfish OS running on high end tablets and phones from generic Chinese manufacturers just to demonstrate the potential that's there.

Anyone who expects big name Android manufacturers to put out a Sailfish device are living in dream world. The best hope is a generic manufacturer who hasn't signed up to the Open Handset Alliance to take a chance with them. Google will never allow the OHA partners to put out a device that does what Jolla does with Android.
