I think I'm more a fan of her having a decent ponytail and RED hair.
When Alcala drew her as a blonde, she frankly just looked too much like He-Man's sister.
The best DRAWINGS of Teela are Alcala's renditions of her in the Point Dread book with the two stories in it. Danger at Castle Grayskull and The Power of Point Dread.
Again, she was blonde there, but paint her hair red and you've got exactly what I'm hoping the new Teela will look like... (with a removable Snake Head Dress of course.

)
Her Filmation hairdo is something all it's own, and I don't really care for it.

See to me, her Filmation hairdo and her toy have two very different styles to them.
So there is no option there for me to vote for.
I want Red hair up in a pony tail with decent length to it. (As Alcala drew, not painted, in the above mentioned book.)
See...
In the end though... I could see her coming with two heads. A more Filmation head and the "classic" ponytail.
I'm thinking if we want a blonde Teela, you'd better buy two and get the paints out.
And if the 4HM are looking at the cardbacks... That's exactly what Alcala was looking at for this book in particular.

He-Man looks his best in this book, as does Teela, Skeletor and Man-E-Faces.
The cool thing too is Alcala drew Merman's toy head on the 8-back body... Which is exactly what we're getting with the two heads that come with Merman... How freakin' cool is that?!!!
