It's a yearly rumor, had been a yearly rumor since the 1050 motor was released. The only thing that changes is speculation on displacement.
I really doubt Triumph has any interest in making a liter+ super sport at this point, and a big-bore supercruiser like the K1300S or VFR1200 is a weak market too. I'm sure they followed the "success" of the new VFR1200 very closely.
