I can see it happening. That section of East New York is very, very transit accessible as you can see in the planning map in the article and I'd argue that's subway accessibility has been the main predictor of where gentrification is taking place/going to take place. Not to oversimplify what factors into gentrification, but I think part of the reason most of Queens isn't really discussed in terms of gentrification is because vast parts of Queens are basically two-fare zones, a good distance away from the closest subway lines.
On a Manhattan-bound J or L train, Bushwick is a stop away from Broadway Junction and the rest of ENY, so it's a natural choice for someone fleeing rising rents in Bushwick and Williamsburg. The only thing that changes about their commute is about 10 - 15 minutes added to their trip.
This part also jumped out at me:
Anecdotally speaking, I can believe this. I take the L train home regularly now and I've noticed an uptick in the number of whites on the train past Bushwick. Where before you'd barely see any of them past the Bushwick Avenue-Aberdeen Street stop, now I've noticed more and more of them going to Broadway Junction. And few of them are hauling luggage that would suggest they're just transferring to the A for a ride to JFK
