According to Zachary Quinto, there is a “goldmine of drama” to be explored in Star Trek 2.
Quinto is happy that there is a bit of delay in making that sequel though. “It makes people miss it a little bit,” he said, “you know what I mean? We had a lot of goodwill around that first movie. So I feel like people are going to be ready for a second one by the time it comes out. It’s not like ‘Already? Really? Again?”
Star Trek 2 could “go anywhere,” says Quinto, and Vulcan’s fate as laid out in Star Trek XI is not necessarily set in stone. “I imagine we’re going to pick up right where we left off, but it could be a completely different timeline,” he said. “They’ve basically now created a device that allows them to go anywhere with it. I mean, we could be in a parallel universe; we could be in a parallel time. That’s the joy of science-fiction. Vulcan could be back.”
