I can see the stretch to make Tina a playable, but I agree that I don’t think they will.
I figure we’ll have either
1.) Old vault hunters that we already know, though possibly with modified skill trees, or
2.) Some completely NEW vault hunters, not previous NPCs, but four to six BRAND-SPANKING-NEW ones, and we’ll see old vault hunters in supporting roles, kinda like Mordecai in Tundra Express and Wildlife Exploitation Preserve.
It’s neat to consider the what-if of turning some of our favorite NPCs into the next game’s vault hunters, but I simply don’t think we WILL see it. There’s no reason they COULDN’T do that with a BL3. But GoetzIronHand has a solid point, that it would be better, if they’re making new playables, to start with blank slates, rather than have to work with the partial back-stories that we already have for our existing NPC cast.
I can definitely see Tina being PRESENT in BL3, and perhaps having some considerable supporting role. And I see that they COULD turn her into a VH, but they most likely WON’T. Fun as it would be to ride piggyback on Brick and toss grenades at dudes while he punches the s**t out of them, I’m not holding my breath on that one.
