What
the writer tweeted is still very vague, but it doesn't necessarily speak to a continuation in my mind. And taking into account the wider mythos, a continuation wouldn't really fit into the continuity established by "Fray," which the current "Reckoning" arc of Buffy's comic (the final season of her comic) looks set to establish.
If I had to guess, I'd say they're going for a reboot with a different cast of characters. The lead may or may not be named Buffy, but the others won't be Willow, Xander, Giles, etc.
