I know nothing is confirmed yet. But has been rumoured for months on end now without confirmation, Remember that piece of paper that was posted on facebook with the orders and number of buses ordered and i'm pretty sure Geminis for 20/56 were on it along with the Citaros for M1 and Streetlites for the 53/54 and 60.
As for the Fast Cats and Cobalt Clipper i'm doubtful on whether those rumours are true or not.
