They said they are considering it, they are going to reuse the starting area which makes it ideal for them to come with additional Dracthyr at that point. And if the class/race proves unpopular I would hope they would act to salvage it. I fully expect significant rework at 10.1 but giving more options can work. I am not saying give them druid (it can work lorewise, they have the green flight as part of them after all) because that's a ton of work. But giving them hunter/mage/rogue/warrior would automatically cover all armor types and all playstyles (they have healer, they'd get more options for dps, they'd get physical range, pet spec, 2h and DW and ofc tank) and is probably the easiest to pull off.
