I do hope we finally visit the Greyjoys! 
But... there hasn't been much in that direction in the teasers...
...
What we have:
- Tyrion in Meereen
- Cersei waging war against the religious power she helped raise.
- Bran doing something cryptic
- Theon and Sansa trying to escape Winterfell.... while Theon's sister (Asha, in the books.... Yara, in the show) attacks(?)... searches for Theon(?)
- Daenerys goes over the whole impress the Khal thing again... boring!
- Arya goes on to learn some more lessons on how to become faceless..... now eyeless!
- Is Jaime back with Cersei?
Meanwhile, they say nothing about what's going on
- At the wall - Jon Snow dead for good? What's Melisasndre up to?
- Brienne... what's she doing? waiting, for a sign of Sansa?
- Dorne gets left behind.... again. I was kinda liking the sand snakes...
- Sam's story... off to the Citadel to become a proper Maester... I don't even remember if that happens in the show!
