Universal wasn't teasing Kong a year out. If they start teasing now, people will get tired of it. People are already tired of how long ago it was announced and how long it is taking. Now you want them to tease things a year out? That won't help them. I believe if they are on target to meet the April date they have right now, that you will see stuff advertised at the end of the year.
Keep in mind they also don't want to take away from their own stuff opening this year like Frozen and Soarin.
