Yep same. Let's not forget that devs said Vol'jin's story wasn't over yet. Trolls need some lore development, and the zandalari are the perfect opportunity for it.
Edit: Also, there was a shaman zandalari set, a doomhammer zandalari skin, a zandalari druid cat form, a raptor-bird mount that came from somewhere mysterious. And most importantly, there were BOTH Kultiras sailors AND zandalari trolls shipwrecked in Aszuna.
